325-3780 383.50 mm OD D-Ring Rubber Seal
Cat® D-rings for final drive planetary gears and brake wheels minimize fluid loss, ensuring efficient use of hydraulic oil.
Description
D-rings are used in dynamic applications. These seals have a curved inner or outer profile to optimize performance and sealing capability.
Cat® D-rings are made from materials compatible with the fluids, temperatures and pressures in Cat engines and machines. These materials resist wear and extrusion, giving the seals excellent compression set resistance. In addition, some Cat D-rings are coated with PTFE to minimize seal twisting and cutting during installation.
Our D-rings are dimensioned to strictly follow tight tolerances, ensuring they are properly seated in the seal groove with the right seal compression.
Cat sealing systems prevent leaks and contamination of more expensive parts. Genuine Cat seals protect your investment.
