Cummins®

The 2887951 O-Ring Seal, manufactured by Cummins, is a vital component in the commercial truck industry. This part is designed for various applications within commercial trucks, ensuring the integrity of seals in critical systems.

Basic Concepts of O-Ring Seals

An O-Ring Seal is a toroidal (ring-shaped) elastomer with a circular cross-section. It functions by creating a seal between two or more parts in mechanical systems. When compressed between a static and a dynamic part, the O-Ring deforms to fill any irregularities in the mating surfaces, thereby preventing the passage of fluids or gases. This mechanism is essential in maintaining the efficiency and reliability of various mechanical systems ¹.

Purpose of the 2887951 O-Ring Seal in Truck Operations

This Cummins part plays a specific role in the operation of commercial trucks. It is utilized in areas where fluid or gas sealing is required, such as in engine components, transmission systems, and hydraulic circuits. By ensuring a tight seal, it helps maintain system pressure, prevent leaks, and protect sensitive components from contamination ².
