⚙️ Key Features

• Genuine Volvo Penta pressure hose
• High-pressure steering construction
• Factory-crimped end fittings
• Correct length and routing
• Designed for DPH-C electronic steering

🔌 Function

The hose carries pressurised hydraulic fluid from the steering pump or control valve to the steering actuator.

⚠️ Common Signs of Failure

• Hydraulic-fluid spray or seepage
• Heavy steering
• Delayed actuator movement
• Bulging hose wall
• Abrasion or cracked outer cover
• Steering pressure or system fault

🛠️ Service Notes

• Cleanliness decides how long the job lasts — cap the open ends, keep dirt out of the ports, and wipe fittings before making them up, because contamination is what wrecks steering and trim components
• Fit the hose without twist, holding the hose body while tightening the union so it is not wound up as the nut turns, and renew the sealing washers or O-rings rather than reusing them, tightening unions to the figure in the workshop manual for your engine
• Route the hose with a generous sweep, clear of hot parts and sharp edges, and clip it so it cannot chafe or be pulled at either end through the full range of movement
• Top up and bleed the system afterwards, cycle it through full travel several times, then recheck the fluid level and inspect the connections for weeps under pressure
• Never search for a pressurised leak by hand — fluid escaping under pressure can penetrate skin

📦 Condition
