Encapsulated O-Rings
The Encapsulated O-rings are made of a silicone rubber or fluororubber core wrapped in an FEP or PFA outer shell. This combination of a rubber's flexibility with a PTFE (Teflon) resistance to chemicals makes for strong, long-lasting O-rings. Encapsulated O-rings can handle extreme temperatures, chemicals, and wear and tear very well. They are a great option for sealing different things because they last much longer than regular rubber and plastic O-rings.
The encapsulating materials include:
FEP and PFA
The core materials come in two types:
Silicone Rubber (SIL) and Fluororubber (FKM).
The encapsulated O-rings are resistant to most chemicals, except for elemental fluorine compounds and molten alkali metals like sodium.
Temperature range:
FEP: -20°C to +200°C
PFA: -20°C to +260°C
Encapsulated O-rings are used in many different ways. They are used in pumps and valves, heat exchangers, boilers, filters, reaction vessels, pressure vessels, piping systems, flanges, mechanical seals, gas compressors, and extraction equipment.
