Description
O-rings are used for static sealing and some dynamic applications.
Features
Cat® O-rings are made from materials compatible with the fluids, temperatures and pressures in Cat engines and machines. These materials resist wear and extrusion, giving the seals excellent compression set resistance. 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 adhere to tight tolerances, ensuring they fit properly in the seal groove with the necessary seal compression.
With more than 2500 different sizes and materials of O-rings, Cat O-rings are the best solution for the O-ring needs of your Cat and other mobile equipment.
Cat sealing systems prevent leaks and contamination of more expensive parts. Protect your investment with Genuine Cat seals.
Applications
O-rings are used in many static and dynamic joints in Cat machines and engines.
