Description
Packaging Description:
O-rings are used for static sealing and some dynamic applications.
Features
Cat® O-rings are made from materials suited to 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 warping 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 required seal compression.
With 2500 O-rings in many different sizes and materials, Cat O-rings are the preferred solution for the O-ring needs of Cat equipment and other mobile equipment.
Cat sealing systems prevent leaks and contamination of more expensive parts. Genuine Cat gaskets protect your investment.
Use:
O-rings are used in many static and dynamic joints in Cat machines and engines.
