What is a rubber gasket used for?
A rubber gasket is a smart component that seals against both liquids and gases. They are the perfect solution to fill in irregularities and connect two surfaces together. The characteristics of a gasket are to be manipulable and able to warp into the tight space it is designed for.
What are rubber gaskets called?
Whether Nitrile, Neoprene, Buna, EPDM, SBR, FKM, Aflas or Natural, they are all often referred to as rubber seals. Rubber Gaskets and Materials - Rubber is perhaps the most commonly used gasket material (especially nitrile gasket material) and is available in many different types and compositions.

Features of the Rubber:
| EPDM | Good resistance to hot water and steam, detergents, caustic potash solutions, silicone oil and greases, many polar solvents, and many diluted acids and chemicals, along with a high level of ozone resistance. EPDM materials are totally unsuitable for use with all mineral oil products (lubricants, fuels). |
| FKM | Good chemical resistance to mineral oils and greases, synthetic oils and greases, engine, transmission and ATF oils to approx. +150°C, fuels, non-flammable hydraulic pressure fluids HFD, aliphatic, aromatic and chlorinated hydrocarbons, water to max. +80°C, excellent resistance to weathering, ozone and ageing, very low gas permeability (and therefore excellent for vacuum application) and resistance to a wide range of chemicals. |
| HNBR | HNBR is obtained by fully or partially hydrogenating NBR. It leads to considerable improvement in resistance to heat, ozone and ageing, and gives it very good mechanical properties, e.g. good resistance to wear. The media resistance compares to that of NBR. HNBR has a good resistance to some refrigerants. The temperature application range is from -30°C to +150°C. |
| NBR | Good chemical resistance to mineral oils and greases, hydraulic oils H, HL, HLP, non-inflammable hydraulic pressure fluids HFA, HFB, HFC to approx. +50°C and water to max. +80°C |
| VMQ | Good resistance to water (up to 100 °C), aliphatic engine and transmission oils, animal and plant oils and fats. VMQ is generally not resistant to fuels, aromatic mineral oils, steam (short term up to 120 °C possible), silicone oils and greases, acids and alkaline compounds. |
