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.
