N - Nitrile (Buna-N, NBR) Most common seal material for its fuel and oil resistance.
Temp Range -30º to +250ºF.
V - Viton®
(Fluorocarbon) Excellent chemical resistance and upper
temperature limit. Temp Range -15º to +400ºF.
E - EPDM Excellent resistance to
polar solvents but petroleum compatibility is poor. Temp Range -70º to
+300ºF.
S - Silicone Excellent thermal stability but mechanical
properties are generally poor.
Temp Range -65º to +450ºF.
