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. 


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 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.

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.
  • Gasket materials are various materials with sealant qualities that are used in gasketing applications.
  • Head gaskets are inserted between the cylinder head and the engine block. Head gaskets prevent coolant from entering the cylinders.
  • High temperature gaskets help prevent leakage of fluids and gas by providing an airtight seal between gaps in machine parts whose temperatures may exceed 500° F.
  • Hollow tube gaskets have a tubular cross section that is typically made out of rubber or plastic.
  • Jacketed gaskets combine the durability of a metal jacket with the sealing capability of a soft gasket.
  • Laminated gaskets consist of two or more layered materials and are often enclosed in an envelope.
  • Neoprene gaskets are made of synthetic rubber and create a long-lasting seal for gaps on machine parts in several industries.
  • O-rings also referred to as "donut-shaped" gaskets, are circular rings, having a variety of cross-sectional configurations that are specified by their dimensions, material and hardness. O-rings are installed in a gland to close off a passageway, preventing the escape or loss of fluids or gases.
  • Profiled and serrated gaskets are solid metal gaskets with surface grooves, which facilitate a good seal with low seating stress. To protect flange surfaces, profile and serrated gaskets can be jacketed.
  • Rubber gaskets are rubber components that create a seal between two parts.
  • Silicone gaskets (formed-in-place) are made from an uncured blend of a silicone compound that is applied to the mating parts and allowed to cure after assembly.
  • Solid metal gaskets are gaskets made out of solid metal, yet they must be softer than the materials of the two adjoining surfaces. Solid metal gaskets are used for extreme pressures or temperatures.
  • Spiral wound gaskets are made of a thin metallic strip and a soft nonmetallic filler that are wound together. Spiral wound gaskets can withstand high pressure and extreme temperature.
  • Teflon gaskets are gaskets designed to resist sticking to the adjoining materials.
  • Viton gaskets are made of a synthetic tube that is resistant to heat, oil, and various acids.
