Durable Back Up Ring For High-Pressure Hydraulic Systems‌ PTFE Corrosion-Resistant

Durable Back Up Ring For High-Pressure Hydraulic Systems‌ PTFE Corrosion-Resistant

 

Product Description

A PTFE-coated hydraulic seal engineered to withstand extreme pressure (10,000+ PSI), abrasion, and temperature fluctuations in excavator systems. Corrosion-resistant and ISO-compliant, it ensures leak-proof durability for cylinders, joints, and pumps under harsh mining/construction conditions.

 

Product Properties

Of all the known plastics, PTFE has some remarkable properties: it will not attacked by corrosive acids, even if they were hot; it did not dissolve in solvents; it could be cooled to -180°C without becoming brittle and it could be heated to 260°C without impairing its performance. PTFE materials also are extremely stable and nonflammable; clean, dry, non-oily and non-staining. The material is biologically inert and does not support biological growth (that is, it is non-pyrogenic). PTFE offer an extremely low static coefficient of friction, which stems from the extremely low intermolecular forces in the PTFE molecule itself.

 

Character of PTFE Gasket

a) Oil Free
b) High temperature resistance
c) Wear-resisting
d) insulate
e) non-stict
Application of PTFE Gasket
1. Agricultural, pumps, mining
2. Rail and transport use, Wheels
