Pressure, temperature and chemical environments need to be considered when selecting O-ring material.
The standard O-ring material for Yale® closures is Nitrile (NBR) which has both excellent resistance to the effects of most hydrocarbons and very good flexibility at low temperature. The maximum operating temperature is 250° F.
FKM (Viton®) O-rings are recommended for higher temperature applications to 400° F.
Ethylene Propylene (EP) Rubber compounds are available for glycol and steam service up to 300° F.
Other elastomers are available for specific service conditions.
