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 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 go through a reliable 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.
