A-Premium Power Steering Pressure Hose Assembly for Nissan V6 3.5L Maxima/Altima Coupe — 1500 PSI, OEM-Style Fit

A-Premium Power Steering Pressure Hose Assembly for Nissan replaces the pump-to-rack high-pressure line to restore reliable steering fluid flow and prevent leaks.

This A-Premium hose assembly is designed specifically for Nissan V6 models — including Maxima (2009–2014) and Altima coupe (2008–2012) with 3.5L engines — and meets OEM-style specifications for fit and performance. Built with multi-layer rubber, galvanized steel tubing and a double-locking crimp, the line resists temperature swings, corrosion and impacts while handling high hydraulic loads. It ships without a mounting bracket and includes reference numbers to help confirm compatibility with your vehicle.

How does this hose reduce steering fluid leaks?

The A-Premium pressure hose uses a multi-layer rubber core wrapped around galvanized steel tubing and finished with reinforced crimping to minimize seepage at joints and along the hose body. The double-locking mechanism at fittings reduces the chance of separation under pressure, and materials are chosen for chemical resistance to power steering fluids.

• Double-lock crimp fittings for secure fluid containment
• Multi-layer rubber resists cracking and permeation
• Galvanized steel reinforcement prevents kink and collapse
• Designed to meet original dimensions for proper sealing

What specifications and pressure ratings should I expect?

This line is engineered for demanding steering systems: it’s rated for a maximum working pressure of 1,500 psi, with a burst performance far above typical system loads. Tensile strength and burst ratings provide a margin that helps the hose endure sudden pressure spikes and mechanical stress during steering maneuvers.

• Position: pump to rack (direct replacement fit)
• Max working pressure: 1,500 psi
• Burst pressure rating: 8,700 psi (tested), burst strength rating: 10,000 psi
• Tensile strength: 1,600 lb for mechanical durability

Will this fit my Nissan model and what reference numbers match?
