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)
Select Rubber
| Material | Working Temperature | Property |
| NBR | 40℃ ~ +120℃ | Oil resistance Heat resistance(medium) Low temperature resistance |
| ACM | 20℃ ~ +150℃ | Oil resistance Good heat resistance |
| FKM | 30℃ ~ +200℃ | Oil resistance High temperature resistance |
| HNBR | -40℃ ~ +170℃ | Oil resistance High temperature resistance Chemicals resistance Low temperature resistance |
| VMQ(Silicone) | -50°C ~ +230°C | lammability ,low gas permeability and excellent resistance to ozone,weathering and aging. |
| EPDM | -50~ +150 °C | EPDM shows good heat ,ozone and aging resistance ,in addition they also exhibit high levels of elasticity, good low temperature behavior as well as good insulating properties. |
