136-7227 Caterpillar O-ring
Cat® O-Rings are used in static sealing and some dynamic applications.
Cat® O-Ring 136-7227 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 136-7227 are detailed below.
Applications: High temperature applications requiring resistance to air, fuels, lubricants and hydraulic fluids
Coating: PTFE coating protects the O-Ring from installation damage and provides ease of assembly.
