Cummins®

The Cummins 3933705 Plain Hose is a component designed for use in commercial trucks. It serves a specific function within the truck’s fluid systems, contributing to the overall operation and efficiency of the vehicle. Understanding its purpose and role is fundamental for maintaining and optimizing truck performance.

Basic Concepts of Plain Hoses

Plain hoses are a type of flexible tubing used in various fluid systems to transport liquids or gases from one point to another. They are characterized by their simple, unadorned design, which lacks reinforcements such as wire spirals or textile braids. This simplicity allows for flexibility and ease of installation, though it may also limit their use to applications where lower pressure and temperature conditions are present ¹. Plain hoses differ from reinforced hoses, which are designed to withstand higher pressures and temperatures due to their additional layers of protection ².
