537-0168: Valve Seal

Cat® Valve Seals are used in static sealing and some dynamic applications. Cat® Seal and O-Rings are made from materials that are matched to the fluids, temperatures and pressures found in Cat® engines and machines. The materials resist wear and extrusion, and provide superior resistance to seal compression set. In addition, certain Cat® O-Rings are coated with PTFE to minimize seal twisting and cutting during seal installation. Dimensions of our O-Rings are consistently held to tight tolerances to ensure they fit properly into seal grooves with the necessary seal compression. With over 2500 O-Rings in different sizes and materials, Cat® O-Rings are your best solution for your Cat® and other mobile equipment O-Ring needs. Application: Cat® Seals and Rings are used in a wide variety of sealing applications throughout Cat® machines. Cat® Sealing systems protect more expensive parts from leaks and contamination. Protect your investment with Genuine Cat® Seals. Consult your owner's manual or contact your local Cat® Dealer for more information.
