Cummins®

The 3526555 O-Ring Seal, manufactured by Cummins, is a component used in commercial trucks. It is part of the sealing systems that help maintain the integrity of various truck systems. Seals play a role in preventing leaks and ensuring that systems operate efficiently by containing fluids and gases within 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. It functions by being compressed within a groove, creating a barrier that prevents the passage of fluids or gases. O-Rings are typically made from elastomers, which are materials known for their flexibility and resilience. Common materials include nitrile rubber, silicone, and fluorocarbon, each offering different properties such as temperature resistance, chemical compatibility, and durability ².
