Industry Information


Innovations in gasket design and manufacturing have contributed significantly to improved safety and efficiency of all kinds of industrial products: vehicles, pumping equipment and pipelines are just a few examples. Of particular importance to the gasket manufacturing industry have been advancements in the field of synthetic rubber development. Gaskets materials must always be carefully chosen with regard to the conditions in which the gaskets will be applied. Viton gaskets, EPDM gaskets, neoprene gaskets, silicone gaskets and other synthetic rubber gaskets each offer different qualities of tensile strength, heat resistance, non-reactivity, corrosion resistance, extreme temperature performance and chemical compatibility. In addition to the increasing availability of new gasketing materials, innovative gasket configurations have given professionals control over the most demanding and irregular connections. Spiral wound gaskets, high temperature gaskets, jacketed gaskets, Teflon gaskets and other special configurations allow for the creation of reliable seals even in the presence of extreme weather conditions or hazardous chemicals. Gaskets can also be specialized according to their application. For example, exhaust gaskets are only used for exhaust management purposes, and head gaskets are almost exclusively used to seal engine blocks and cylinder heads in combustion engines.

Across industry, gaskets of all shapes, sizes and compositions are used for sealing applications. The aerospace, automotive, aviation, electronics, military, transportation and countless other industrial operations make extensive use of gaskets. Airframes, appliances, business machines, compressors, elevators, escalators, medical equipment, meters, turbines, pumps, valves, engines, plumbing systems and a host of other varieties of equipment require the use of gaskets in order to function safely and effectively. Seals between joints are critical in many hydraulic, pneumatic and aerospace applications responsible for maintaining air or fluid pressure; in commercial aircraft, for example, gaskets throughout the aircraft keep the cabin from depressurizing. Gaskets have historically played a very important role in the safe operation of equipment. Gasket failure can have catastrophic consequences, as was the case in the explosion of the Challenger space shuttle in 1986. The failure of an O-ring gasket used in the shuttle's fuel system was attributed to low-temperature exposure, which made it become brittle. Engineers give very careful consideration to all of the factors that contribute to gasket operation; when gaskets fail, their failure can be devastating.

Most rubber gaskets are die cut from flat rubber or metal sheets. Die cutting allows gasket manufacturers significant design flexibility, and gaskets are cut in shapes as simple as basic rings or as complex as automotive engine blocks. For applications that require simple gaskets with thick, strong construction, rubber molding is used as an alternative to die cutting. Gasket manufacturers use a wide number of both natural and synthetic rubbers to manufacture gaskets with application-specific tolerances. Common elastomeric materials include silicone, neoprene, nitrile, EPDM and Viton. Plastics commonly used for either gasket material or for jacketing include Teflon, nylon, polyethylene (PE), polyurethane and mylar. Sponge rubber like open or closed cell silicone is also used for applications requiring a more flexible seal. Gaskets may be made out of non-asbestos sheets such as carbon filament, fiberglass, ceramics and Kevlar. Metal gaskets and shims, which are flat metal gaskets similar to washers, are used alone or in combination with rubber gaskets to fill additional gaps that may occur within flanges, which is similar to the way metal jacketed gaskets are used to create extra seal strength and corrosion resistance.

Gaskets range in their design from very simple to very complex. The simplest gasket variety is the O-ring, which, as its name suggests, is merely a thin, O-shaped ring. They are almost always made of natural or synthetic rubber, though some metal and plastic ring gaskets could be described as O-rings. More complex gaskets can be textured to fit more effectively in a connection point; such shaped gaskets can be tapered, grooved, ridged or otherwise shaped to create a seal between two objects. In situations in which the point of a connection may be subject to stress, tension or movement, spiral wound gaskets can maintain a tight seal and provide the flexibility necessary to allow movement without breaking. These seals feature interwoven or combined metal and filler materials to provide a combination of strength, flexibility and effective sealing. Head gaskets are among the most complicated gasket varieties. They are used to create a seal between engine blocks and cylinder heads in combustion engines. They must combine features of strength, heat resistance and chemical resistance as they are exposed to the chemicals and heat involved in fossil-fuel combustion engines. Whatever the gasket configuration, every design is engineered to accommodate the conditions of a specific application, and the importance of anticipating all of those conditions cannot be overstated.

Six Varieties of Multiple-Use Industrial Gaskets

In industrial terms, a gasket is a mechanical seal used to bridge the gap between two surfaces. Different types of seals are utilized to make a joint or compartment leak-proof. Resting in a space between two parts, gaskets create a pressure-tight seal that does not allow any leakage into/from the application it is used for. Household pressure cookers are the most common appliance that intelligently uses gaskets to pressure-cook your food.

Gaskets are not just limited to pressure cookers; they are used in a large number of applications and processes across industries. Additionally, for each application and process, different types and styles of gaskets are utilized. In the below subsections, listed are six variations of gaskets based on make or material type.

  1. Rubber Gaskets
  2. Rubber is known for its impressive elastomeric characteristics; therefore, it can be adopted in applications that involve high pressure. Rubber Gaskets can bear heavy loads applied by weighty, substantial machine parts. Rubber can also maintain a tight seal under high-pressure zones for a long duration of time.

  3. Plastic Gaskets
  4. Thermoplastic elastomer, thermoplastic rubber, and various similar materials are a combination of plastic and rubber. Rubber and plastic are the two most popular materials for gaskets. These materials are also a favorite choice of gasket manufacturers. Plastic alone is also employed for the manufacturing of gaskets. The seals of made of these compounds are strong and display the properties of rubber as well as plastic. However, due to their low melting point, they are not used for applications that include high temperatures.

  5. Metal Gaskets
  6. Manufactured of metal and metal alloys, metal gaskets are considered ideal for processes within high pressure or high temperature zones. Some of the most common metals and ores used for gaskets are aluminum, stainless steel, brass, copper, and nickel, etc. These are some of the strongest materials available, and they offer superior resistance against heat, pressure and corrosion. In addition, they offer outstanding durability and flexibility; making them a suitable choice for the formation of mechanical seals.

  7. Solid Gaskets
  8. Solid gaskets are made from hard, rock-solid metals, with properties like superior thermal and pressure resistance. Although forming metal pieces into a seal-like shape takes hard effort and strong pressure, solid gaskets are an affordable replacement for jacketed gaskets. In addition to this factor, they are best suited for use between two metal parts.

  9. Jacketed Gaskets
  10. Jacketed gaskets come with attractive advantages of strength and flexibility. Jacketed gaskets are made from rubber/plastic and have an external metallic coating. Sub-varieties include single-jacketed, double jacketed and French jacketed.

  11. Silicone Gaskets
  12. Silicone gaskets are made to bear extreme temperature. Silicone gaskets are a valuable utility, as they can perform their duties under a broad variation in temperature - from -140 degrees to 480 degrees Fahrenheit. Apart from these factors, silicon can also provide shielding and resistance from ultraviolet light. Furthermore, these gaskets can be used with the gaskets of other materials to enhance the strength of pressure and temperature bearing.

How to Select the Best Gasket Manufacturer for Your Industrial Application

Gaskets are used to create high-pressure seals between parts or surfaces. These utilities put an end to the potential for leaks from or into an application or area. Gaskets play a very important role in the smooth and proper functioning of gadgets and equipment we use in our everyday lives. Technically, gaskets are mechanical seals that are placed between two surfaces to fill up (any possible) gaps between them. Rubber is the most effective material for gaskets; however, gaskets are also made from metal, semi-metals, wood, foam, fiber, silicon, and other composite materials.

When it comes to the smooth and reliable functionality of an appliance, choosing the right gaskets becomes a necessity. To select the most appropriate gaskets, choosing the right manufacturer or supplier turns can be an intricate process.

The following article suggests a few ways to find the right gasket manufacturer or supplier to meet your specific application needs.

Heat Resistance: The gasket that you select should be able to bear the temperature that your process employs. Different gasket materials support different degrees. For example, Neoprene (CR) can support any temperature between-35 degrees Fahrenheit and 225 degrees Fahrenheit, and Gar lock Gylon can work efficiently between -450 degrees Fahrenheit and 500 degree Fahrenheit. You should check with your supplier regarding the temperature resistance a gasket's material.

Environmental Resistance: In addition to heat, you should inquire whether the gaskets you select will support environmental factors (gas, liquid, air, pressure, etc.) related to your application. EPDM Gasket or Ethylene Propylene Dien-terpolymer Membrane is an exceptionally resilient synthetic rubber that is safe and good for almost all environments. Suggestions from your internal engineers or external gasket suppliers will aid in the selection process.

Pressure Resistance: You also need to understand how much pressure the gasket material you are evaluating can withstand. The gasket should be hard enough to bear the load applied by the mating surfaces. Additionally, you should rely on compression and pressure test results performed by a trusted lab.

There are two major ways to locate a reliable gasket manufacturer: either you perform a search on Google or you can locate an online business directory. However, to find a reliable online business directory also, you will have to help from Google or any other search engine.

The Google Method

  • Enter your desired keyword. For example: gasket manufacturers/suppliers in (your city).
  • You will find the sites of different vendors, delivering gaskets in your city/state.
  • Check out their site and offerings, and request a quote from at least three to four suppliers.
  • Partner with the one that matches your requirements.

Through Directory:

  • Search for business directory of your city/state/country. is one such business directory. Locate the search box at the top of every page and enter your search term.
  • Browse through the list of manufacturers and suppliers, and contact them.
  • Evaluate their price quote, and sign the contract.

How to Find the Appropriate Gasket for Your Unique Application

The significance of gaskets in our daily lives cannot be denied or overlooked. Everything that we use or see-from mobile phones and kitchen appliances to automobiles, industrial machines, airplanes, submarines, rockets, and spaceships-has some kind of gasket in its structure or internal mechanisms. Primarily, gaskets are used as a seal to ensure that there is no space left between two compartments in an application. They prevent the leaks and emission of water, oils, air, gases, and fluids in and from the appliance they are being used for.

Choosing the right size or type of gasket is crucial, as the entire functioning of a device or machine depends on it. Just one mismatch can undermine your investments in time and materials.

Following find a series of steps to follow when evaluating and selecting types of gaskets for your manufacturing processes.

Have the Measurements On-Hand: Many times, gaskets fail to create a perfect seal just because of their wrong size. The primary task of these seals is to establish even and strong pressure between two joining surfaces. However, a number of other factors such as temperature, metal or material of the mating surfaces, and the mass applied by these two surfaces also play a key role in determining the right gasket. However, the right size of gasket is the most important factor in a gasket's operation. Therefore, you should seek suggestions from your process engineers when preparing measurements and selecting appropriate gaskets.

Consider the Material Properties: Gaskets are available in an array of materials including plastic, rubber, thermoplastic rubber, metal, alloys, silicone, wood, foam, fiber, etc. Note that all gasket materials are suitable for all industrial applications. Some processes employ extreme temperatures, while some appliances need shock-resistance, and many need rock-solid joints. Different materials render varying benefits, and thereby, the material of the gasket should be considered when selecting gaskets for a specific manufacturing application.

Determine Chemical Resistance: Metal and metallic gaskets are useful for heavy-duty use. While gaskets made of these materials can provide superior sealing for tough and weighty industrial procedures, they may not be suitable for processes that involve acidic or alkaline solutions. It is important to test the chemical resistance of the material in question. Match the chemical resistance of your gasket's material with the severity of chemicals in your process fluid. Polytetrafluoroethylene (PTFE) is one such material that has a strong resistance against fluids of 0 to 14 pH levels. However, this material may not be ideal for certain heavy applications.

Perform Performance Tests: Another important task in evaluating industrial gaskets is to test the performance of each gasket. This step is crucial to ensure the gasket that you have chosen for your application is most suitable. Some of the tests that should be performed include hot and cold compression, and a creep relaxation test. These tests can help you determine the temperature, pressure and negative force resistance of the gasket.

Understanding the Different Types of Industrial Gaskets

Gaskets play a crucial role within almost every industry, including automotive, electronics, home appliances, aerospace, aviation, defense, and consumer goods. These utilities are used as a sealing device. Typically made of rubber, gaskets have a ring like shape, material, and size which depend on their manufacturing application. However, gaskets can be made from various other materials, such as metal, plastic, foam, etc.

Gaskets are used where tight pressure is required and ensure that the environment inside the housing does not come into contact with the outside environment. In other words, gaskets help create a seal between different stationary components, preventing the leak of gases, air, liquid, and contaminants into and from the application. Pressure-tight closures enforced by gaskets can strongly resist the impact of pressure, temperature, and several other factors, such as an electromagnetic field. The soft, malleable material of gaskets conveniently and efficiently works between the parts where it is placed.

Importance of Gaskets

As stated earlier, gaskets work as a sealing utility that prevents the leak or emission of gases and liquids in or from an application or manufacturing process. In any application that needs to maintain and prevent its interior elements from exterior elements, gaskets will play a key role. Spaceships, airplanes, refrigerators, laptops, packaged water bottles, and almost every electronic appliance or machinery around you uses some type of gasket in order to operate smoothly. However, not every appliance will use similar gaskets. There various types of gaskets are described in detail in the paragraphs below.

Solid Gaskets: Usually, solid gaskets are formed from soft and elastic materials. However, solid gaskets are also made from metal, given them strong capabilities to stand firm under high pressure and temperature. Simply put, solid gaskets are typically used in machines that create or work under/on an extreme pressure and temperature. The type of metal used for the creation of these gaskets has to be stronger and denser than the metal used in the application that houses them.

Jacketed Gaskets: If you need elasticity afforded with the robustness of solid metal gaskets, jacketed gaskets should be your choice. These seals are both efficient and flexible given their rubber or plastic construction and external metallic coating. These gaskets are also available in two types-single-jacket and double-jacket. The single-jacket gasket has only one side coated, and the double-jackets are completely coated. The double-jacket has an improved resistance to high temperatures, decay and pressure. French-style gaskets come with jacketing on both the inside and outside of the gaskets.

Rubber and Plastic Gaskets

For applications in which you need to create a strong seal but not within a high temperature or high pressure environment, rubber gaskets and plastic gaskets are a good choice. These are the most popular gaskets and are used in a large number of appliances. Many gasket manufacturers only offer rubber and plastic gaskets due to their very high demand.

The Many Types of Gaskets

Gaskets are mechanical components used to create seals at the point of connection between two pieces of equipment. In applications in which liquids or gasses are transmitted through pipes, hoses or tubing, gaskets prevent leaking and loss of pressure at connection points. Because so many industries make such wide use of so many chemicals under so many circumstances, an entire industry of connection management solutions designers has emerged to accommodate them.

Gasket design and manufacturing have contributed significantly to improve the efficiency and safety of all sorts of industrial products including machines, vehicles, and pipelines. A gasket provides a mechanical seal that fills the space between two or more joining surfaces to ensure a tight seal, usually to avoid any possible leakage to or from the objects. Some types of gaskets include Teflon, exhaust, neoprene, viton, rubber, head, silicone, high temperature, spiral wound, EPDM, metal and more. Most often, gaskets are made out of flat materials and each gasket is punched out of a sheet of material to be made. Rubber gaskets are often made by die cutting from flat rubber or metal sheets. The process of die cutting allows a manufacturer to have design flexibility. Many industries use gaskets a great deal including automotive, aerospace, transportation, aviation, military, plumbing systems, and appliances. Gaskets play a very important role in any system that uses them, especially when toxic chemicals or liquids are involved and a spill could place harm on surrounding people and the environment.

Gaskets range in their design from very simple to very complex, come is all shapes and sizes, and are used for many different sealing applications. The simplest type of gasket is the o-ring which is commonly made out of natural or synthetic rubber, is very thin and has an O-shape as its name suggests. Complex gaskets can be textured to fit more effectively in a connection point; such shaped gaskets can be tapered, ridged, grooved, or otherwise shaped to create a tight seal between two objects. Gaskets materials must always be specifically chosen with regard to the conditions in which the gaskets will be applied. Whatever the gasket configuration, each design is engineered to accommodate the conditions of a specific purpose, and the importance of anticipating all of those conditions cannot be overstated. 

Gaskets Types

  • Composite gaskets are custom-fit to individual applications and are typically applied with a gasket dressing or adhesive in assembly and sealing. Composite gaskets are made from any combination of the following materials: cork, rubber, paper and felt.
  • Corrugated gaskets are metal gaskets that may be surface-treated with ceramic, non-asbestos or flexible graphite. Corrugated gaskets, which may be used with Teflon envelopes, provide a seal at low seating stress.
  • Die cut gaskets are made of materials that can be cut before assembly.
  • ElastaGraph gaskets are corrugated gaskets that are suitable for high temperature, high pressure applications and consist of a metallic core over which a seamless flexible graphite is applied. ElastaGraph gaskets have a high density inner ring to increase sealability and provide low minimum seating stress.
  • Encapsulated gaskets consist of a gasket of one material and a continuous layer of another material, typically Teflon, which completely encloses the gasket.
  • Envelope gaskets consist of a gasket of one material and an envelope of another material, typically Teflon, which covers the gasket.
  • EPDM gaskets are made of a synthetic rubber that serves as a seal between two mating surfaces in machine parts.
  • Exhaust gaskets provide a seal on exhaust parts in vehicles to guarantee that when gases leave the engine, they stay in the exhaust system until they are expelled into the atmosphere.
  • Fibre seal rings are diecut, water-jet cut or formed gaskets or rings that provide a seal between two surfaces.
  • Flange gaskets have protruding rims or lips that aid in the attaching process.
  • Foam gaskets are made out of strips of plastic, foam or rubber.
