Encapsulated O Rings

Encapsulated O Rings have a Core and an Outer Casing, this allows for a Hybrid Seal that uses the best properties of both materials. The outer casing is chosen for its resistance to the media involved and is often made of Teflon FEP or PFA, for chemical resistance. The Core gives the seal its energy and is usually either Viton or Silicone.
