Power steering hoses

Relevance of power steering hoses in steering and axle systems

In this section of our online catalogue we offer a specialised range of power steering hoses designed for industrial and heavy-duty vehicles. These components are critical parts for connecting the hydraulic pump to the steering gearbox, enabling the correct flow of oils at the pressures required for system operation.

Our offering is aimed at professional mechanics, workshop managers and fleet managers looking for equivalent-quality spare parts for the maintenance of trucks and buses. Replacing these lines in time is vital to ensure vehicle manoeuvrability and avoid major damage to the steering and axle circuit due to leaks or pressure loss.

Criteria for choosing the correct hydraulic line

• OEM reference: The safest way to get it right is to check the original reference number and identify the exact equivalent in the replacement part.
• Type of line: It is necessary to distinguish whether the high-pressure hose (pump outlet) or the return line (low pressure) is required.
• Geometry and length: The hose must match the original bends and length to avoid chafing against other engine or chassis components.
• Fittings and connections: Check that the threads and end fastening systems match the ports on the steering gearbox and the pump.
• Material specifications: Make sure that the rubber and metal reinforcements are designed to withstand the temperatures and fluids specific to heavy-duty vehicles.

Frequently asked questions

When is it necessary to replace the power steering hoses?

Immediate replacement is recommended if hydraulic oil stains are observed on the floor, moisture is present on the fittings, or if the rubber shows cracks, excessive stiffness or bulges. Regular visual inspection prevents sudden loss of steering assistance.

What is the difference between the pressure hose and the return hose?

The pressure hose carries compressed fluid from the pump to the steering gearbox to generate assistance force. The return hose returns the fluid to the reservoir at lower pressure. Structurally they are different and are not interchangeable.

How can I ensure compatibility with my truck or bus?

Compatibility is mainly verified through the manufacturer reference (OEM) or by filtering by make, model and year of the heavy-duty vehicle. It is essential that the technical specifications of the replacement part match those of the installed hydraulic system.

Is it safe to repair a pitted steering hose?

In the professional heavy-duty vehicle sector, patch repairs on high-pressure lines are not recommended. For safety and operational reliability, the standard practice is to replace the damaged component with a new hose that guarantees leak-tightness.
