Viton® / FPM O-Rings

Viton® O Rings have a low compression set and have high temperature and chemical resistance. More expensive than NBR O Rings.

The terms FPM, FKM and Viton® very often cause confusion and lead to incorrect interpretations. All of these designations actually stand for one single base material:fluoro rubber.

Temperature Range -20ºC to +200ºC (avoid prolonged use at higher extremes)
