O Rings

The encapsulated O rings are made of silicone rubber or fluororubber core and 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.
