Description for part number 9X-7557

Description:
Fuel system Seals are specifically designed and manufactured to work in the fuel system. Both O-ring and rectangular cross-section designs are used.

Attributes:
Cat® Fuel System Seals go through additional advanced inspections to ensure reliable performance in this critical application. They are made from materials that are matched to the fluids, temperatures and pressures found in Cat fuel systems. The materials resist wear and extrusion, and provide superior resistance to seal compression set. In addition, some seals are coated with PTFE to minimize seal twisting and cutting during seal installation.

Dimensions of our seal 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:
Fuel System Seals are used in engine fuel systems.
