The Importance of Rubber Gaskets
Rubber gaskets are rubber products used to seal spaces between two
surfaces. Such seals are necessary in many kinds of equipment,
especially those that involve tubing and hoses through which liquids or
gasses pass. For example, when two sections of tubing meet, their point
of connection must often be sealed by some kind of gasket material to
ensure that no fluid leaks out though their connection point.
Most gaskets on the market today are made out of some type
of rubber. Whether it is acrylic, butyl, chlorinated polyethylene, silicone,
polyurethane or natural rubber, they are all classified under the term rubber.
This property is very common for gaskets because of their purpose of sealing
two adjoining items tightly and securely. Rubber is so flexible that it can be
squeezed tightly against surfaces so make sure no liquids or gases get through
any openings that could potentially be present at two adjoining surfaces. Many
rubber gaskets have a large varying temperature range that they can still
perform in no matter hot or cold conditions. Certain rubbers carry better temperature
ranging properties than others, so the best rubber gasket can be chosen depending
on the application. This is very important as gasket failure could potentially
cause a lot of damage or issues within a system.
Rubber gaskets are found on windows, doors, cars, plumbing
systems, engines, hoses, and many other places. They are especially critical
for use when fluid is being transferred through connecting pieces when the
fluid is toxic or dangerous to interact with. The gasket will ensure that no
leakage or spills happen protecting the safety of the surrounding people and environment.
Rubber gaskets come in a wide range of sizes and thicknesses and are most
commonly made in a circular shape. Manufacturing companies will usually make a
custom gasket to fit the needs of any project for a customer or client. Rubber
gaskets are heavily used in the industrial industry on manufacturing machines
and equipment. There are many different manufacturing processes to make certain
items and they usually require working with substances and gases that can be
harmful. The uses of rubber gaskets help ensure that these machines run
smoothly and safely.
All engines depend on gaskets for sealing components that transmit fuel, oil and gasses like exhaust. In many gasketing applications, rubber is the most effective sealing material because of its fluid non-permeability, chemical resistance, heat resistance and capacity for withstanding pressure. All rubber products are elastomers, and elastomers are characterized by elasticity. This quality of elasticity is what makes rubber such an ideal material for gasketing applications. Most rubber products, when compressed and then relieved, will return to their original shape fairly quickly, assuming extreme temperatures and the presence of corrosive chemicals are not factors. If, for example, a simple O-shaped rubber gasket is used to seal the lid of a ceramic pot, the rubber pushes against the pot and its lid, which creates a seal. This is how all rubber gaskets create seals.
Different rubber materials perform in different ways when used in gasketing applications. Because gaskets are used to prevent chemicals and gasses from leaking, the material used to create the gaskets must resist degradation caused by contact with those materials. Gasoline and other petrochemicals can degrade many rubber varieties. In response to the demand for rubber materials that could resist corrosion despite contact with petrochemicals, synthetic rubber materials like EPDM
were developed. Heat and corrosion resistance are key considerations when applying gaskets in a given context. Viton, the first fluoroelastomer ever developed, is an excellent material for the sealing of fuel lines and other avenues through which petrochemicals are transmitted. Viton cannot, however, come into contact with ketones, acetone and other organic acids. EPDM displays excellent compatibility with ketones but poor compatibility with petrochemicals. Because gaskets contribute to the safe and stable operation of machines with which people come into constant contact, the importance of carefully selecting gasketing material cannot be overstated. Improperly selected or maintained gaskets can cause catastrophic failure in the equipment in which they are applied; when carefully chosen and periodically checked for signs of stress or degradation, they contribute very significantly to equipment’s safe and effective operation.
