Introduction

The Cummins 5484395 O Ring Seal is a component designed to ensure the integrity of fluid systems within commercial trucks. Its purpose is to create a reliable seal between mating parts, preventing leaks and maintaining system efficiency. The significance of this seal in truck operation lies in its ability to support the consistent performance of critical systems, contributing to the overall reliability and longevity of the vehicle ¹.

Basic Concepts of O Ring Seals

An O Ring Seal is a type of gasket consisting of a ring of elastomer with a round cross-section. It functions by being seated in a groove and compressed during assembly between two or more mating parts, creating a seal at the interface. O Ring Seals are widely used in mechanical systems to prevent the leakage of fluids and gases, and to exclude contaminants from sensitive areas ².
