Description: Rectangular Seals and Rings are circular seals with a rectangular cross-section. The edges may or may not be rounded according to the application needs.
Attributes: Cat® Seals and Rings are 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.
Dimensions of our Seals and Rings are consistently held to tight tolerances to ensure they fit properly into seal grooves with the necessary seal compression.
Cat Sealing systems protect more expensive parts from leaks and contamination. Protect your investment with Genuine Cat Seals.
Applications: Rectangular seals and rings are used in a wide variety of sealing applications throughout Cat machines and engines.
