Descriptions
O-Rings are used in static sealing and some dynamic applications. O-Rings are made from materials that are matched to the fluids, temperatures and pressures found in engines and machines. The materials resist wear and extrusion, and provide superior resistance to seal compression set.
In addition, certain 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.
