PFA coated FKM o-rings FEP encapsulated silicone o-rings
O-Ring with a FEP or PFA () outer layer encapsulating a silicone or FKM o ring core. The shell offers excellent chemical and temperature resistance while the FKM core provides the resiliency needed to provide effective sealing. Readily available in common USA and metric cross-sections and nearly unlimited diameters. FEP encapsulated Solid Silicone with improved chemical resistance up to 205℃. PFA encapsulated Solid viotn/silicone up to 260℃.
Temperature:
FEP Encapsulated O-rings: -60℃ to 205℃ (260℃ short term)
PFA Encapsulated O-rings: -60℃ to 260℃ (300℃ short term)
