5 Most Commonly Used Gasket Materials and Their Respective Properties

06 August 2021

Gaskets have been very useful for industries that require effective sealing on their projects. After all, these products are known for filling the space or gap between two or more coupling surfaces, helping them prevent leakage during their operations.

As previously stated, many industries maximise gaskets due to their main function. One of these industries is the automotive industry. Gaskets are often utilised in vehicles so that the leakages on their engine and other system components will be prevented. The manufacturing industry likewise utilises gaskets to thoroughly sustain the movement of machines without expecting any sudden leaks.

The requirements of each industry and their respective applications may vary. Hence, gaskets nowadays are made from various materials. Some of the most commonly used materials for gaskets and their respective properties are as follows:


Metal gaskets are known for being durable since they can withstand extreme temperatures, chemicals, and pressure. They can likewise expand and contract easily thanks to their accompanying properties. With these features alone, these gaskets can effectively be used in machines that carry out medium and high-pressure applications. Some notable uses of metal gaskets include turbines, compressors, heat exchangers, and other similar machines.


Cork gaskets, alternatively, are popular for their strong resistance to fuel, oil, and solvent. Additionally, they can withstand the effects of acids, fungus, and extreme weather elements, as well as impact and vibration. Their flexible properties likewise make them great for most industries. All these properties of cork gaskets allow them to be extremely useful for sumps, crankcase covers, valve covers, general cover and lids, electrical switchgear, and inspection doors.


Felt gaskets are comprised of natural and synthetic materials that can resist tearing. They likewise have notable strength, sound insulation, vibration dampening, and thermal insulation. With their overall material composition, felt gaskets can also be considered eco-friendly, generating minimal carbon footprint and emissions to the environment. Gaskets made from felt can be utilised in applications that often generate rattles and squeaks. They can also be used for filtration purposes.


Another gasket material that is used by many industries is polyurethane. Polyurethane gaskets are comprised of a polymer that possesses organic units tied together by urethane links. Their primary composition allows them to recover to their original shape whenever they are deformed. These gaskets likewise have excellent wear resistance, notable rebound capabilities, and reliable load-bearing qualities. Polyurethane gaskets, however, cannot work well against extremely high-temperature applications.


One more material that can be used in gaskets is rubber. Rubber gaskets are known for their reliability and durability due to their overall composition. These gaskets have excellent resistance to extreme weather elements and temperatures. They can likewise withstand ageing and wear. These properties make them extremely useful for household applications as well as industrial uses, especially for those that are intended to prevent leakage of liquids.
