[Materials & Temperature] Nitrile (Buna-N) -40°C to 135°C Nitrile (Low-Temp) -65°C to 120°C [Use With These Fluids] petroleum oils, water, hydraulic oils [Applications] 
Nilrile is presently the seal industry's most widely used elastomer. Nitrile oil seals combine excellent resistance to petroleum based oils and fuels, silicone greases, hydraulic fluids, water and alcohols. Nitrile has a good balance of working properties such as low compression set, high tensile strength, high abrasion resistance, combined with a low cost.
