Description
O-rings are used for static sealing and some dynamic applications. Cat® O-rings are made from materials matched to the fluids, temperatures and pressures in Cat engines and machines. These materials resist abrasion and extrusion and provide excellent compression set resistance for the seal. In addition, some Cat O-rings are coated with PTFE to minimize seal twisting and cutting during installation.
Our O-rings are dimensioned to strictly follow tight tolerances, ensuring they are properly seated in the seal groove with the right seal compression. With more than 2500 different sizes and materials of O-rings, Cat O-rings are the best solution for your O-ring needs on Cat and other mobile equipment. Cat sealing systems prevent leaks and contamination of more expensive parts. Protect your investment with Genuine Cat seals. O-rings are used in many static and dynamic joints in Cat machines and engines.
