What Is EN 856 4SP / 4SH Hydraulic Hose?
The EN 856 4SP and 4SH spiral hydraulic hose are four-spiral high-tensile steel wire reinforced, very high-pressure hydraulic hoses manufactured to the EN 856 standard. They are the go-to choice for the most demanding hydraulic applications in India and globally — hydraulic presses, heavy construction equipment, mining machinery, offshore equipment, and industrial systems where working pressures exceed the capability of double wire braid hoses. The 4SP designation covers bore sizes 3/8″ to 1-1/4″, while 4SH covers 1/2″ to 2″, with both types sharing the same four-spiral construction principle.
The Flexihose spiral hose pipe construction uses a black oil-resistant NBR (nitrile butadiene rubber) inner tube, four spirals of high-tensile steel wire reinforcement for maximum pressure resistance, and a weather-resistant, oil-resistant, abrasion-resistant synthetic rubber outer cover. Working pressures range from 140 bar (2″ bore) to 420 bar (3/8″ bore), with minimum burst pressure of 4× working pressure per EN 856, and a service temperature range of −40°C to +100°C.
Flexihose India manufactures EN 856 spiral hose — also known as high pressure spiral hose — at our ISO 9001:2015 certified plant in Bhiwadi, Rajasthan — approximately 60 km from Delhi. For OEM buyers, hydraulic press manufacturers, construction equipment distributors, mining equipment companies, and GCC export buyers, we supply factory-direct with test documentation, dimensional compliance to EN 856, and India-wide dispatch.
EN 856 4SP / 4SH Hydraulic Hose — Supply Configurations by Bore Size
The same EN 856 four-spiral construction is supplied across multiple bore sizes. Working pressure varies by bore — select the right size for your system pressure and flow requirement.
Ideal for hydraulic presses, crane circuits, and high-pressure industrial systems where maximum working pressure in a compact bore is required. The 3/8″ bore delivers up to 420 bar — the highest pressure rating in the Flexihose range.
The most commonly ordered bore range for heavy construction and mining equipment — excavator main circuits, drill rig hydraulics, rock breaker lines, and high-pressure industrial machinery where R2 double braid is insufficient.
Used for hydraulic presses, offshore equipment, heavy industrial machinery, and high-flow high-pressure circuits where both large bore and very high working pressure are required simultaneously.
For heavy industrial machinery, large hydraulic power packs, and OEM hose assemblies where large bore and high working pressure are both required. The 4SH designation covers this range per EN 856.

How to Select EN 856 4SP / 4SH Hydraulic Hose — Procurement Guide
A practical step-by-step guide for procurement managers, plant engineers, OEM buyers, and construction equipment companies selecting EN 856 4SP/4SH hose for their application.
Confirm System Working Pressure
EN 856 4SP/4SH is rated from 140 bar (2″ bore) to 420 bar (3/8″ bore). If your system pressure exceeds 400 bar at 1/4″ bore or 165 bar at 1″ bore, 4SP/4SH is the correct specification. For pressures below 215 bar at 1/4″ bore, SAE 100 R1 or R2 may be more cost-effective. Always apply a safety factor — do not operate at the maximum rated working pressure continuously.
Choose Between 4SP and 4SH
EN 856 4SP covers bore sizes 3/8″ to 1-1/4″ and is the standard specification for most high-pressure applications. EN 856 4SH covers 1/2″ to 2″ and is used where larger bore sizes are required at high pressure. Both share the same four-spiral construction — the designation is determined by bore size range per the EN 856 standard.
Select Bore Size by Flow Rate
3/8″–1/2″ for high-pressure pilot and control lines on presses and cranes. 5/8″–3/4″ for main circuits on heavy construction and mining equipment. 1″–1-1/4″ for industrial presses and offshore equipment. 1-1/2″–2″ for large hydraulic power packs and heavy OEM assemblies. Undersizing bore increases pressure drop and heat generation.
Verify Fluid Compatibility
The NBR inner tube is compatible with petroleum-based hydraulic oils (HLP, HM, HV grades), water-glycol mixtures, fuel, and lubricating oils. For phosphate ester fluids or water-based fire-resistant fluids, confirm inner tube compatibility before ordering. Not suitable for aromatic solvents or strong acids.
Specify Fitting Type and Assembly
EN 856 4SP/4SH hose accepts standard BSP, JIC (37° flare), and NPT fittings. For very high-pressure applications, ensure fittings are rated to the same working pressure as the hose. Flexihose can supply cut lengths, coil reels, or complete hose assemblies with crimped fittings to your specification. Specify end connection type when ordering.

EN 856 4SP / 4SH Hose Construction & Materials
Layer-by-layer construction of Flexihose EN 856 4SP/4SH hydraulic hose — what each component does and why it matters for very high-pressure hydraulic system reliability.
NBR Inner Tube
Black oil-resistant NBR (nitrile butadiene rubber) synthetic rubber compound. Formulated to resist petroleum-based hydraulic oils (HLP, HM, HV grades), water-glycol mixtures, fuel, and lubricating oils. The inner tube is the primary fluid barrier — its integrity determines hose service life under continuous high-pressure cycling in press, crane, mining, and industrial hydraulic systems.
Four-Spiral Steel Wire Reinforcement
Four spirals of high-tensile steel wire wound in alternating directions. This four-spiral construction delivers significantly higher pressure resistance than double wire braid hoses — up to 420 bar at 3/8″ bore per EN 856. The alternating spiral winding provides balanced reinforcement that resists both internal pressure and torsional stress in demanding hydraulic circuits.
Synthetic Rubber Outer Cover
A weather-resistant, oil-resistant, abrasion-resistant synthetic rubber outer cover rated −40°C to +100°C. Protects the steel wire reinforcement from mechanical damage, UV exposure, oil splash, and mild chemical contact in field conditions across Indian construction sites, mining environments, industrial plants, and offshore applications.
In-House Testing & Certification
Every production batch is tested at our Bhiwadi in-house laboratory with NABL-calibrated equipment: hydrostatic burst pressure test (minimum 4× working pressure per EN 856), impulse pressure cycling, dimensional checks, and outer cover adhesion tests. Test certificates with actual measured values are issued as standard with every order — not templated data.
EN 856 4SP vs SAE 100 R2 vs SAE 100 R1 — Which Hydraulic Hose to Choose?
Buyers often need to choose between 4SP/4SH, R2, and R1 hydraulic hose. Here is a practical comparison to help with selection for Indian industrial, construction, and mining applications.
| Parameter | EN 856 4SP / 4SH | SAE 100 R2 AT | SAE 100 R1 AT |
|---|---|---|---|
| Reinforcement | 4 × spiral high-tensile steel wire | 2 × high-tensile steel wire braid | 1 × high-tensile steel wire braid |
| Max WP at 3/8″ bore | 420 bar (6,090 PSI) | 330 bar (4,785 PSI) | 180 bar (2,610 PSI) |
| Max WP at 1″ bore | 250 bar (3,625 PSI) | 165 bar (2,395 PSI) | 88 bar (1,275 PSI) |
| Temperature Range | −40°C to +100°C | −40°C to +100°C | −40°C to +100°C |
| Flexibility | Moderate (stiffer at large bore) | Moderate | Good |
| Typical Use | Presses, cranes, mining, offshore, very high-pressure circuits | Presses, cranes, high-pressure industrial circuits | Tractors, excavators, general industrial hydraulics |
| Relative Cost | Highest | Higher | Medium |
EN 856 4SP/4SH is the correct choice when system pressure exceeds the capability of R2 double braid hose, or when EN 856 is specified by the equipment OEM. For most medium-pressure circuits in Indian agriculture and construction, SAE 100 R1 or R2 is more cost-effective. Not sure?

Frequently Asked Questions — EN 856 4SP / 4SH Hydraulic Hose
EN 856 4SP and 4SH hydraulic hoses are four-spiral high-tensile steel wire reinforced, very high-pressure hydraulic hoses manufactured to the EN 856 standard. They consist of a black oil-resistant NBR inner tube, four spirals of high-tensile steel wire reinforcement wound in alternating directions, and a weather-resistant, abrasion-resistant synthetic rubber outer cover. 4SP covers bore sizes 3/8″ to 1-1/4″; 4SH covers 1/2″ to 2″. They are used for hydraulic presses, cranes, mining equipment, and other very high-pressure applications.
EN 856 4SP and 4SH share the same four-spiral steel wire construction and are both manufactured to the EN 856 standard. The difference is in bore size coverage: 4SP covers 3/8″ to 1-1/4″ nominal bore, while 4SH covers 1/2″ to 2″ nominal bore. For bore sizes in the overlapping range (1/2″ to 1-1/4″), both designations may apply — the equipment OEM specification or procurement standard will determine which to use. Both types are available from Flexihose India.
The maximum working pressure of EN 856 4SP hydraulic hose varies by bore size: 420 bar at 3/8″ bore, 350 bar at 1/2″, 315 bar at 5/8″, 280 bar at 3/4″, 250 bar at 1″, and 215 bar at 1-1/4″. For 4SH, working pressures continue at 180 bar at 1-1/2″ and 140 bar at 2″. The minimum burst pressure is 4× the working pressure per EN 856.
EN 856 4SP has four spirals of high-tensile steel wire and is rated up to 420 bar at 3/8″ bore — required for the most demanding high-pressure hydraulic circuits in presses, cranes, and mining equipment. SAE 100 R2 has a double steel wire braid and is rated up to 400 bar at 1/4″ bore — suitable for high-pressure circuits where EN 856 is not specifically required. At larger bore sizes (1″ and above), 4SP/4SH offers significantly higher working pressure than R2. If your equipment OEM specifies EN 856, use 4SP/4SH.
EN 856 4SP/4SH hydraulic hose price in India varies by bore size, order quantity, and delivery location. As a direct manufacturer, Flexihose India offers factory-direct pricing without trading margins — significantly lower than distributor or trading company sources. Bulk orders and annual rate contracts attract further discounts. WhatsApp +91 8094002348 with your bore size, quantity, and city for a current price quote.
EN 856 4SP/4SH hydraulic hose accepts standard BSP (British Standard Pipe), JIC (37° flare), and NPT fittings. For very high-pressure applications, ensure fittings are rated to the same working pressure as the hose — standard BSP fittings may not be rated to 420 bar at small bore sizes. Flexihose can supply complete hose assemblies with fittings crimped to your specification — specify end connection type (male/female, BSP/JIC, straight/elbow) and required working pressure when ordering.
