Encapsulated O Rings

Product Information

Rhondama are one of the UK’s largest stockists and distributors of Encapsulated Silicone & Viton O-Rings

An encapsulated O-Ring is made up of an elastomer energising core and a seamless jacket made from a Fluoropolymer. The core can be made from either Silicon or Viton whilst the jacket is usually made from FEP.  There are certain applications which prohibit the use of conventional rubber O-ring Seals. The use of hostile chemicals or extreme temperature (both high and low) during various processes can make effective sealing very difficult. The main advantage Encapsulated ‘O-Rings have over solid P.T.F.E. is that it has the chemical inertness whilst with its energising core, the O-ring returns to its original form.
