Cat® pressure seal for the valve cover base provides a safe, reliable fit.
Description
Press-in seals stay fixed in the groove to improve assembly performance and prevent leakage and contamination. They are a custom design specific to the application requirements.
Features
Press-in seals are made of materials compatible with the fluids, temperatures, and pressures in Cat® engines and machines. These materials resist abrasion and extrusion and give the seals excellent compression set resistance.
Cat® sealing systems go through a robust design, testing and validation process. Protect your investment with the latest Genuine Cat® seals.
Applications
Press-in seals are widely used in many static joints on Cat® engines and machines. They are specifically designed for inverted or vertical assemblies.
