Description
Cat® O-rings are manufactured from materials suitable for the fluids, temperatures and pressures encountered in Cat engines and machines. These materials resist wear and extrusion, and provide superior resistance to joint compression. Additionally, some Cat O-rings are coated with PTFE to reduce the risk of twisting and cutting when installing the seals.
