Introduction

The Cummins 4996016 O Ring Seal is a component designed to ensure the integrity of seals in various systems within commercial trucks. Its role is to prevent leaks and maintain system efficiency, contributing to the overall reliability and performance of truck operations.

Basic Concepts of O Ring Seals

An O Ring Seal is a type of gasket consisting of a ring with a circular cross-section. It is made from elastomers or rubber-like materials and is used to create a seal between two or more parts. The seal functions by being compressed during assembly between a male and a female part, creating a barrier that prevents the passage of fluids or gases. Common materials for O Ring Seals include nitrile rubber, silicone, and fluorocarbon, each offering different levels of resistance to chemicals, temperatures, and compression set ¹.
