418-6845 High Pressure Hose — Cat 6020 6020B

This is a high-pressure hydraulic hose, designed to safely transport hydraulic fluid under extreme operating pressures within the machine's system. It is constructed with robust materials to meet demanding OEM specifications for burst strength and durability, far exceeding the capacity of a worn or damaged hose. Operators may notice hydraulic fluid leaks, spongy or unresponsive controls, or a loud hissing sound under pressure when this hose fails.

Installation & Application Notes

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing high-pressure hose is often a small, weeping leak of hydraulic fluid, especially under load. If ignored, the leak will worsen, potentially leading to a sudden hose rupture and a rapid loss of hydraulic fluid and system pressure. A burst hose can cause significant damage to surrounding components and create a serious safety hazard due to high-pressure fluid spray.

Installation Tip

Ensure the hose routing is correct and that the hose is not twisted or rubbing against any components during installation. Avoid using excessive force when tightening hose fittings, as this can damage the threads or the fitting itself.

Service Note

Inspect all adjacent hydraulic hoses and fittings for signs of wear, leaks, or damage, and check the hydraulic fluid level and condition.
