112-1102 Caterpillar O-ring
Cat® O-Rings are used in static sealing and some dynamic applications.
Cat® O-Ring 112-1102 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 112-1102 are detailed below.
Applications: Automotive air conditioner seals; High temperature flex boot seals; High temperature power steering seals; Higher temperature hydraulic seals; Middle cylinder liner seals
Coating: PTFE coating protects the O-Ring from installation damage and provides ease of assembly.
Color Notes: Actual o-ring color may differ from image.
