Description
Rectangular seals and seal rings are ring-shaped seals with a rectangular cross-section. Depending on the needs of the application, the edges may be rounded or not rounded.
Features
Cat® seals and seal 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.
Our seals and 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.
Applications
Rectangular seals and seal rings are widely used in a variety of sealing applications on Cat machines and engines.
