Cummins®

The 4302719 O-Ring Seal, manufactured by Cummins, is a component designed for use in commercial trucks. Cummins, a well-established name in the diesel engine and component manufacturing industry, produces this seal to ensure the integrity of various systems within trucks. Seals play a significant role in maintaining system integrity by preventing leaks and ensuring that fluids and gases remain contained within their designated pathways ¹.

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. Typically constructed from elastomeric materials, O-Rings are chosen for their flexibility and ability to conform to the surfaces they seal against. Common materials include nitrile rubber, silicone, and fluorocarbons, each offering different properties suitable for various applications. The principle behind an O-Ring’s function is its ability to deform under compression, creating a seal that can withstand both static and dynamic conditions ².
