Hydraulic Hose Solutions for SAE, EN and Industrial Fluid Systems
Hydraulic hose is a flexible, reinforced conduit designed to transfer hydraulic fluid between pumps, valves, cylinders, motors and other components in pressurized fluid-power systems. It is commonly used where rigid tubing cannot accommodate machine movement, vibration, installation space or repeated flexing. For B2B buyers, the category includes one-wire and two-wire braided hose, multi-spiral high-pressure hose, compact hose, return and suction hose, and application-specific hose for mining, high-temperature or petroleum-related conditions.
A suitable hydraulic hose helps equipment manufacturers, hose assembly distributors, repair workshops and industrial maintenance teams match fluid compatibility, pressure capacity, bend requirements and environmental exposure to a specific operating system. VIH’s range covers commonly requested SAE and EN hose constructions, including SAE 100 R1, R2, R16, R17, R19, R12, R13 and R15, as well as EN 853, EN 854, EN 856 and EN 857 series. Smooth-cover and wrapped-cover alternatives allow buyers to select a hose surface according to abrasion exposure, handling preference and market requirements. The available product range also includes selected special-purpose products such as mining hydraulic rubber hose, wire steam hose, petrol pump hose and yellow wire air hose.
How to Select the Right Hydraulic Hose
Hydraulic hose selection should start with the complete operating condition rather than the pressure rating alone. The hose, fittings, crimping method and installation routing need to work as one assembly. Buyers should confirm the following points before selecting a hose type or requesting a quotation:
- Working pressure and pressure peaks: Select the reinforcement type according to continuous working pressure, impulse conditions and possible pressure spikes. One-wire or two-wire braided hose is commonly considered for standard hydraulic lines, while multi-spiral constructions are generally used for more demanding high-pressure equipment.
- Applicable standard: Confirm whether the equipment specification requires SAE 100 R-series hose, EN 853, EN 854, EN 856, EN 857, ISO 18752 or another applicable standard.
- Fluid and temperature: Check compatibility with petroleum-based hydraulic fluids, lubricants, air, steam or other media, together with the minimum and maximum operating temperature.
- Hose inner diameter and flow requirement: Choose the correct ID to maintain the required flow rate while controlling pressure loss and heat generation in the hydraulic circuit.
- Reinforcement construction: Compare one-wire braid, two-wire braid, three-wire braid and four- or multi-spiral constructions based on system pressure, flexibility and impulse-duty requirements.
- Bend radius and routing: Review available installation space, machine articulation points, vibration and hose movement to avoid kinking, twisting or excessive bending.
- Cover type and external exposure: Smooth covers can support easier cleaning and identification, while wrapped covers may be selected where a textured exterior or specific abrasion-handling preference is required.
- Fitting interface: Confirm the required fitting series, thread standard, end configuration and assembly method. Relevant specifications may include metric, American, British or Japanese system connections.
- Testing documentation: For OEM programs, mining equipment, export projects or critical machinery, clarify whether impulse, burst pressure, rubber tensile, ozone-aging, flame-retardant, anti-static or abrasion-resistance test information is required.
- Order quantity and supply plan: Provide estimated annual demand, order quantity, hose size mix and assembly requirements so that production and delivery arrangements can be evaluated accurately.
Hydraulic Hose Types by Structure and Application
The products in this category can be evaluated by reinforcement method, pressure demand and intended use. Braided hose is commonly used in mobile hydraulics and general industrial equipment, while spiral hose is typically selected for systems subject to higher pressure, severe impulse loads or heavy-duty operating conditions.

Hydraulic Hose FAQ
What is the difference between braided and spiral hydraulic hose?
Braided hydraulic hose uses one or more braided layers of steel wire reinforcement, while spiral hydraulic hose uses multiple steel-wire layers wound in alternating spiral directions. Braided hose is commonly selected for standard hydraulic applications, while spiral constructions such as EN 856 4SP, EN 856 4SH, SAE 100 R12, R13 and R15 are generally considered for higher-pressure or higher-impulse operating conditions. The final selection should be based on the equipment requirement, working pressure, pressure peaks, bend requirement and fluid medium. The VIH range includes both braided and spiral hydraulic hose constructions.
How do I choose between SAE 100 R1 and SAE 100 R2 hydraulic hose?
SAE 100 R1 hose generally uses one steel-wire braid, while SAE 100 R2 uses two steel-wire braids. A buyer should compare the equipment’s working pressure, impulse demand, routing conditions and required hose standard before deciding. For example, VIH describes its SAE 100 R1 smooth-cover hose as having an oil-resistant synthetic rubber inner tube, one steel-wire braid and an oil- and weather-resistant synthetic rubber cover for petroleum-based hydraulic fluids from -40°C to +100°C.
What information is needed to source hydraulic hose from China?
For a hydraulic hose China inquiry, provide the target hose standard or reference model, inner diameter, working pressure, fluid medium, temperature range, required length, cover preference, quantity and destination market. If hose assemblies are needed, include fitting type, thread standard, end orientation, fitting material and assembly drawing or sample where available. Buyers should also state whether they need product marking, branded packaging, samples or test documentation.
Can hydraulic hose be supplied with fittings and couplings?
Yes. Hydraulic hose projects can be evaluated as bulk hose supply or hose assembly supply. If fittings are required, the buyer should specify the connection standard, thread type, fitting shape, hose size, material requirement and crimping configuration. Qingdao VIH Hose Co., Ltd lists hose fittings and couplings in carbon steel, stainless steel and brass, including standard and non-standard connection products.
Are smooth-cover and wrapped-cover hoses interchangeable?
They may be available in similar hose standards, but the suitable option depends on the product design, external abrasion exposure, handling preference and customer specification. Smooth-cover and wrapped-cover versions should be compared by the exact product page, construction and intended application rather than by cover appearance alone. The category includes both smooth-cover and wrapped-cover versions for several SAE and EN hydraulic hose series.
What test information should be requested for a hydraulic hose project?
The required documentation depends on the application and customer specification. Buyers may request information related to impulse testing, burst pressure testing, rubber tensile testing, ozone aging testing, flame retardancy, anti-static performance or wear resistance when applicable. The test scope should be defined before production, especially for high-pressure equipment, mining machinery, export projects or safety-sensitive assemblies. Qingdao VIH Hose Co., Ltd reports having equipment for these categories of testing.
