Description: O-Rings are used in static sealing and some dynamic applications.
Attributes: Cat® 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.
Cat Sealing systems protect more expensive parts from leaks and contamination. Protect your investment with Genuine Cat Seals.
Applications: O-Rings are used in many static and dynamic joints throughout Cat machines and engines.
