The Cummins 3094345 O-Ring Seal is a critical component designed to maintain the integrity of seals within commercial truck systems. It plays a significant role in ensuring the efficiency and reliability of truck operations by preventing leaks and ensuring proper system function.

Basic Concepts of O-Ring Seals

An O-Ring Seal is a type of gasket made from a circular section of elastomer. It functions by creating a seal between two or more parts, typically in dynamic or static applications ¹. Within mechanical systems, O-Ring Seals operate by deforming slightly when compressed, which allows them to fill gaps and create a barrier against fluids or gases.
