  • Back-up rings are used in conjunction with O-Ring for both static and dynamic sealing applications.
  • The design of PTFE Back-up rings it used to overcome the problems of O-ring extrusion when the system pressures are greater than the sealing capabilities of an unsupported O-ring.
  • The use of P.T.F.E. for anti-extrusion rings has many advantages over 'hard rubber' materials, particularly at system pressures.

Application:

  • Backup rings can be used singly or on both sides for bi-directional pressure.
  • Like an O-ring they are easy to install and their useage often allows slightly broader machining tolerences and clearences of mating parts

Why Encapsulated?

  • 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.

Recommended for use in:

  • Chemical Processing and Production
  • Oil Extraction (on shore and off shore)
  • Petrochemical Refining
  • Pharmaceutical Production
  • Food and Drink Processing
  • Paint and Die Manufacturing
  • Cosmetics and Perfumery
  • Automotive Components
  • Aerospace Engineering
