204-0946 Hose — Cat 320C 320D

This is a high-pressure hydraulic hose designed to safely convey hydraulic fluid between components in heavy machinery. Manufactured to withstand extreme pressures and flexing, it ensures a reliable connection where a worn or burst hose would cause immediate fluid loss. Operators will typically observe a sudden loss of hydraulic function and visible fluid leakage when a hose fails.

Failure Symptoms

The first sign of a failing hose is often a slow seep or minor leak at a connection point or along the hose body. If ignored, the leak will worsen, leading to a gradual loss of hydraulic power and potential spraying of fluid. A burst hose results in an immediate and complete loss of hydraulic function, creating a significant safety hazard.

Installation Tip

Ensure all mating surfaces and connection threads are clean and free of debris before installing the new hose. Avoid twisting the hose during installation, as this can cause premature failure.

Service Note

Inspect all other hydraulic hoses, fittings, and the hydraulic fluid level and condition when replacing this hose.
