Cummins®

The 4900446 O-Ring Seal, manufactured by Cummins, is a component used in commercial trucks. It is part of the broader category of seals that play a role in maintaining system integrity and efficiency within these vehicles. Seals are vital for preventing leaks and ensuring that systems operate within their designed parameters 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. It is typically made from elastomers, which are materials that can return to their original shape after deformation. The principle behind its function is the compression of the O-Ring between two surfaces, which creates a seal that can withstand pressure and prevent the passage of fluids or gases. O-Ring Seals are used in both dynamic and static applications, providing reliable sealing solutions across various industries ².
