Introduction

The Cummins 3280809 Plain Hose Coupling is a component designed for use in commercial trucks. Its purpose is to facilitate the secure connection of hoses within various fluid transfer systems. This coupling ensures a reliable and leak-free connection, which is vital for the efficient operation of the truck’s systems.

Basic Concepts of Plain Hose Couplings

Plain hose couplings are devices used to join two hoses or a hose to a fitting without the need for clamps. They operate by compressing the hose between two flanges, creating a seal that prevents fluid leakage. These couplings are commonly used in systems where fluids such as coolant, fuel, or hydraulic fluid are transferred. Their design allows for easy installation and removal, making them suitable for applications where frequent disconnection and reconnection are required ¹.
