22 x 2.5 PTFE Solid Back Up Ring

• 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
