Cummins®

The Cummins 145558 O Ring Seal is a component designed to maintain system integrity in commercial trucks. It serves a role in ensuring the proper functioning of various systems by providing a reliable seal. This seal helps prevent leaks and maintain the efficiency of the truck’s operations.

Basic Concepts of O Ring Seals

An O Ring Seal is a type of gasket with a circular cross-section, designed to create a seal between two or more parts. It functions by being compressed within a groove, creating a barrier that prevents the passage of fluids or gases. Common materials for O Ring Seals include elastomers like nitrile, silicone, and fluorocarbon, each chosen for specific applications based on their properties. The principle of elastomeric sealing relies on the material’s ability to deform under compression and return to its original shape, ensuring a tight seal ¹.
