Description: Cat® Dust Seals and rings provide an effective seal between system components functioning under a wide range of operating conditions. They are designed using the right combination of material and shape to deliver the performance you expect for your application. Seals and 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. Dimensions of our Seals and Rings are consistently held to tight tolerances to ensure they fit properly into seal grooves with the necessary seal compression.
