Cummins®

The Cummins 3400816 O Ring Seal is a component utilized in commercial trucks, contributing to the maintenance of system integrity within these vehicles. Seals are vital for the operation of fluid systems, ensuring containment and preventing leaks that could result in system failure or inefficiency ¹.

Basic Concepts of O Ring Seals

An O Ring Seal is a gasket made from a circular ring of elastomer with a round cross-section, designed to create a seal when compressed within a groove. Materials such as nitrile rubber, silicone, and fluorocarbon are commonly used, each offering distinct properties like chemical resistance, temperature tolerance, and compression set ². The functionality of an O Ring Seal relies on its ability to deform under compression, filling the space between mating surfaces and preventing fluid or gas passage.

Purpose of the 3400816 O Ring Seal in Truck Operations

This Cummins part is engineered to maintain the integrity of fluid systems in commercial trucks. It is associated with components like fuel injectors, where fluid containment is crucial. By providing a reliable seal, it ensures the efficient operation of these components, preventing leaks that could cause performance issues or safety hazards.

Key Features of the 3400816 O Ring Seal

The 3400816 is characterized by its design and material properties, crafted from materials resistant to specific fluids and operating conditions encountered in commercial trucks.
