Description
O-rings are used primarily as axial or radial seals in static applications to prevent leakage and contamination.
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 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 the O-ring needs of your Cat and other mobile equipment.
Cat® sealing systems go through a robust design, testing and validation process. Protect your investment with the latest Genuine Cat seals.
Applications
O-rings are widely used throughout the Cat® product line.
