Caterpillar 4J-0522 Seal O-Ring - 37.69mm ID

Features
 • 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
 • With over 2500 O-Rings in different sizes and materials, Cat O-Rings are your best solution for your Cat and other mobile equipment O-Ring needs
