Power steering hoses are high-pressure fluid-transfer lines that connect the steering pump, rack-and-pinion or steering gear, and reservoir in a vehicle's hydraulic steering system. This guide covers hose types, pressure classes, end fittings, OEM specifications, and material construction to help you specify the correct replacement or OEM-equivalent hose.
A power steering hose is a reinforced elastomeric hose assembly engineered to convey hydraulic fluid at continuous high pressure (typically 80–180 bar / 1,200–2,600 psi) between the power steering pump, the steering gear or rack, and the fluid reservoir. The system relies on two complementary lines: a high-pressure (pressure) hose delivering fluid from pump to gear, and a low-pressure (return) hose returning fluid back to the reservoir.
DA Fluid manufactures OEM-equivalent power steering hoses for Japanese, American, and European vehicle platforms, conforming to SAE J188, SAE J189, SAE J2050, GM 6034M, Ford ESF-M2C32, Chrysler MS-5931, and JIS K 6333 standards, with NBR / EPDM / HNBR inner tubes, single or twin steel-wire braid reinforcement, and EPDM / CSM outer covers rated for under-hood temperatures of -40°C to +150°C.
Our catalog covers every hose category used in modern hydraulic steering systems:
Twin steel-wire braid reinforced hose rated 100–180 bar. Carries pressurized fluid from pump to steering gear. The most critical line in the system.
Single textile-braid or unreinforced hose returning fluid from gear to reservoir at 5–15 bar. Larger ID than pressure hose, typically 10–16 mm.
Larger-bore low-pressure hose connecting reservoir to pump inlet. Operates under vacuum; must resist collapse and cavitation damage.
Oil-to-coolant heat exchanger line that routes steering fluid through the radiator or dedicated cooler. Used on heavy-duty and high-performance vehicles.
Factory-crimped hose with formed end fittings (banjo, flare, ORFS, beadlock). Direct-fit replacement for specific vehicle part numbers like 53713-S9A-A03.
Hybrid system: retains hydraulic lines for backup or high-load assist. Requires ultra-clean fluid and tighter pressure tolerance than conventional systems.
DA Fluid power steering hoses are direct OE replacements for the world's major vehicle platforms:
