259-4600 Caterpillar O-ring
Cat® O-Rings are used in static sealing and some dynamic applications.
Cat® O-Ring 259-4600 is 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, all the characteristics and compatibilities of the Cat® O-Ring 259-4600 are detailed below.
Coating: PTFE coating protects the O-Ring from installation damage and provides ease of assembly.
