Metal Seal Ring

Cat designs and manufactures its retainers and seals to endure incredible torque, high impact loads, and frequent directional changes. Cat seal rings are designed for the sealing of liquids and gases in static, rotating, and reciprocating applications.Cat® O-Rings are made from materials that are matched to the fluids, temperatures and pressures found in Cat engines and machines. The materials resist wear and extrusion, and provide superior resistance to seal compression set. In addition, certain Cat O-Rings are coated with PTFE to minimize seal twisting and cutting during seal installation. Dimensions of our O-Rings are consistently held to tight tolerances to ensure they fit properly into seal grooves with the necessary seal compression.
