Colored 75 Duro FKM O Ring viton gasket

Operational application limits 

Temperature EPDM 70: -45 °C to +130 °C
Temperature FKM: -15 °C to +200 °C
Temperature HNBR 70: -30 °C to +150 °C
Temperature NBR: -30 °C to +100 °C
Temperature VMQ 70: -55 °C to +200 °C

Application:non-flammability ,low gas permeability and excellent resistance to ozone,

weathering and aging. They can be used for extreme low temperatures and anti-explosion decompression applications: these rubber rings are manufactured with a very strong grade of FKM and are usually employed, respectively, in contact with e.g. liquid nitrogen and in petroleum extraction plants.

Rubber material

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.
