What Is 4SP 4SH Hose?
4SP 4SH hose is the four-spiral grade of the FLEXI HOSE® hydraulic range, built to EN 856. Construction is an inner tube of oil resistant synthetic rubber, four spiral plies of steel wire wrapped in alternating directions, and an oil and weather resistant synthetic rubber cover. The catalogued application is petroleum based hydraulic fluids.
Two things separate 4SP 4SH hose from a braided grade. The first is pressure: at 1 inch bore it is rated 5510 PSI / 380 BAR against 2400 PSI / 165 BAR for SAE 100 R2. The second is temperature: the published service range is −40 °C to +120 °C, twenty degrees above every other grade in the FLEXI HOSE® hydraulic family.
Alternating spiral plies also behave differently under impulse. A braid resists pressure but tends to unwind slightly under repeated surge; four plies laid in opposing directions balance that force, which is why 4SP 4SH hose is the grade specified on high-cycle equipment such as hydraulic breakers, forging presses and drill rig circuits. In Saudi Arabia that means mining at Mahd adh Dhahab and Al Amar, Eastern Province drilling support, and the heavy earthmoving fleets on the Kingdom’s giga-projects. The full family sits on the Saudi hydraulic hose page.

4SP 4SH Hose Against the Braided Hydraulic Grades
Five hydraulic grades are manufactured in-house. The four-spiral grade is the top of the range on both pressure and temperature. Every figure below is taken verbatim from the FLEXI HOSE® catalogue.
The grade covered on this page. The only FLEXI HOSE® hydraulic product rated to +120 °C, for petroleum based hydraulic fluids on high pressure, high cycle circuits.
The two-braid grade below the spiral range. Lighter and tighter bending, and adequate for the majority of mobile plant service circuits.
The single-braid grade, for moderate pressure circuits where a spiral hose would add weight and bend radius for no service benefit.
Textile braid rather than wire, for low pressure hydraulic and return lines where flexibility is worth more than pressure capability.
The lowest pressure grade in the range. Single textile braid for pilot lines, lubrication lines and low pressure return duty.

The complete FLEXI HOSE® EN 856 4SP / 4SH size table. PSI and BAR pairs are published exactly as printed in the catalogue and are never recalculated or rounded.
| Nominal Bore (Inch) | Nominal Bore (mm) | Mean O.D. (mm) | Working Pressure (PSI) | Working Pressure (BAR) | Min. Burst (PSI) | Min. Burst (BAR) |
|---|---|---|---|---|---|---|

Construction: inner tube of oil resistant synthetic rubber; four spiral plies of steel wire wrapped in alternating directions; oil and weather resistant synthetic rubber cover. Service temperature −40 °C to +120 °C across the full range. Catalogued application is petroleum based hydraulic fluids.
Reading the table: working pressure does not fall smoothly with bore in this range. The 3/4 inch row is catalogued at 6090 PSI / 420 BAR, above the 1/2 inch row at 6020 PSI / 415 BAR and the 5/8 inch row at 5080 PSI / 350 BAR. That is the printed catalogue figure and we publish it as printed rather than smoothing the curve. Confirm the row for the exact bore you intend to order.
When to Specify 4SP 4SH Hose Instead of a Braided Grade
Four questions, in order. A spiral hose is the right answer to some of these and the wrong answer to others.
Media — petroleum based fluid
The catalogued application for 4SP 4SH hose is petroleum based hydraulic fluids. That is narrower than the braided SAE grades, which also cover water based fluid, fuel and lubricating oils. If the circuit runs a water glycol or a synthetic ester, confirm compatibility before ordering rather than assuming the higher grade covers more media.
Pressure — above the two-braid line
The clearest reason to move to 4SP 4SH hose is a circuit that exceeds the two-braid rating at the bore you need. At 1 inch, SAE 100 R2 stops at 2400 PSI / 165 BAR while the spiral grade carries 5510 PSI / 380 BAR. At 2 inch the gap is wider still: 1160 PSI / 80 BAR against 3630 PSI / 250 BAR.
Temperature — the +120 °C case
4SP 4SH hose is the only grade in the FLEXI HOSE® hydraulic range published to +120 °C. Where a circuit runs hot in normal service — a breaker line, a continuously loaded press, a machine working in Saudi summer with limited cooler capacity — that twenty degree margin over the braided grades is a genuine reason to specify it.
Routing — the trade-off
Four spiral plies make the hose stiffer and heavier than a braid at the same bore. Bend radius goes up, and a spiral hose forced round a tight corner at the fitting will fail at the ferrule regardless of its pressure rating. If routing is congested and pressure allows, a braided grade is the better engineering answer.
If the circuit sits below the two-braid line at your bore, SAE 100 R2 or SAE 100 R1 will route better and cost less. Specifying 4SP 4SH hose where it is not needed is a common and expensive habit.
4SP 4SH Hose Applications Across Saudi Arabia
Where four-spiral hydraulic hose earns its cost in the Kingdom, sector by sector.
Hydraulic Breakers and Demolition
Breaker circuits are the classic four-spiral application. Impact frequency puts the line under continuous impulse, and the alternating spiral construction resists that far better than a braid. Demolition and rock breaking on Riyadh redevelopment and quarry faces across the Kingdom both fall here.
Mining — Mahd adh Dhahab and Al Amar
Drill rigs, primary crushers and heavy loaders in the Kingdom’s expanding gold and base metal operations. Circuits run high pressure and hot, and dust attacks the cover, so the oil and weather resistant cover specification matters alongside the 5510 PSI / 380 BAR rating at 1 inch bore.
Drilling Support — Eastern Province
Mud pumps, top drive circuits, pipe handling and BOP control lines on land rigs around Dhahran, Abqaiq and the Ghawar field. These circuits carry the highest pressures on the site and are the reason 4SP 4SH hose is held in Eastern Province stores.
Heavy Earthmoving on Giga-Projects
Large excavators, dozers and mining trucks on NEOM, Qiddiya, Diriyah Gate and Red Sea packages. Where a 40 tonne class machine runs main circuits above 350 BAR, the braided grades are out of scope and the spiral grade is the working specification.
Port Cranes and Container Handling
Spreader circuits, boom hoist and luffing systems at Jeddah Islamic Port, King Abdulaziz Port Dammam and Jubail Commercial Port. Duty is continuous and downtime is expensive, so hose is replaced on schedule rather than on failure.
Presses and Steel Fabrication
Forging presses, shears, balers and injection moulding in the Jubail and Yanbu industrial cities and the Riyadh manufacturing belt. These are fixed installations running high cycle counts at temperature, which is the case the +120 °C rating was written for.
Why Import 4SP 4SH Hose from Flexihose India?
What Saudi procurement teams, rig contractors and EPC buyers get by buying direct from the manufacturer.
Manufacturer, Not Reseller
Spiral hose is extruded, wire-wrapped, cured and tested at our own plant at F-621, Phase-1, RIICO Industrial Area, Bhiwadi, Rajasthan. You buy at manufacturer pricing and you talk to the people who made the batch.
Impulse and Burst Testing In-House
Burst, impulse and dimensional testing is done in our own R&D laboratory, and all test equipment is calibrated by NABL-accredited bodies. For a high cycle product this matters more than for any other grade, and test certificates ship with the consignment.
Published Figures Only
Every pressure, bore and temperature figure on this page comes from the FLEXI HOSE® catalogue, including the 3/4 inch row that sits above its neighbours. We publish what is printed rather than smoothing a curve to look tidier.
Seven Bores in One Range
All seven 4SP 4SH hose bores from 1/2 inch to 2 inch are catalogued, so a rig contractor or distributor can stock a full ladder from one supplier rather than mixing brands across sizes.
Consolidated Shipments
Spiral hose ships alongside R1, R2, R3 and R6 on one bill of lading, together with industrial rubber, suction and discharge and stainless steel hose. Every shipment carries commercial invoice, packing list, certificate of origin, bill of lading and test certificates.

People Also Ask — 4SP 4SH Hose in Saudi Arabia
Short, direct answers to the questions Saudi buyers ask most about four-spiral hydraulic hose.
What does 4SP and 4SH mean?
Both are hydraulic hose designations under EN 856. The “4” refers to four layers of spiral wire reinforcement, and the S denotes a spiral rather than a braided construction. The FLEXI HOSE® 4SP 4SH hose is catalogued as a single four-spiral range covering seven bores from 1/2 inch to 2 inch.
What is the highest working pressure available?
In the FLEXI HOSE® catalogue the highest working pressure is 6090 PSI / 420 BAR at 3/4 inch nominal bore, with a minimum burst pressure of 24360 PSI / 1680 BAR. The 1/2 inch row follows at 6020 PSI / 415 BAR, and the 2 inch row is the lowest at 3630 PSI / 250 BAR.
Why is spiral hose better than braided hose for breakers?
Impulse behaviour. A wire braid resists static pressure well but tends to work slightly under repeated surge. Four plies laid in alternating directions balance that force against itself, so 4SP 4SH hose holds up better on high frequency circuits such as hydraulic breakers, presses and drill rigs.
Can four-spiral hose replace SAE 100 R2 in any circuit?
Not automatically. It is stiffer, heavier and has a larger bend radius, so a route designed around a braided hose may force it past its minimum bend at the fitting. It also has a narrower catalogued media scope, covering petroleum based hydraulic fluids only. Check routing and fluid before substituting.
What temperature can four-spiral hydraulic hose handle?
The published service temperature is −40 °C to +120 °C, which is twenty degrees above every braided grade in the FLEXI HOSE® hydraulic range. That applies to the fluid in the line. External radiant heat still needs to be managed with sleeving or re-routing.
What bores are catalogued?
Seven nominal bores: 1/2 inch, 5/8 inch, 3/4 inch, 1 inch, 1-1/4 inch, 1-1/2 inch and 2 inch. Mean outside diameter runs from 24.00 mm at 1/2 inch to 68.00 mm at 2 inch. Confirm both bore and outside diameter with your fitting supplier before ordering ferrules.

Seven bores from 1/2 inch to 2 inch are catalogued. Contact the export team on +91 9251554066 or mktg@flexihoseindia.com.
At 1 inch nominal bore the FLEXI HOSE® four-spiral hose is rated 5510 PSI / 380 BAR working pressure with a minimum burst pressure of 22040 PSI / 1520 BAR. Mean outside diameter is 38.00 mm. These are catalogue figures, published as printed rather than converted.
That is what the catalogue prints: 6090 PSI / 420 BAR at 3/4 inch against 6020 PSI / 415 BAR at 1/2 inch and 5080 PSI / 350 BAR at 5/8 inch. We publish printed figures rather than smoothing the curve. If the exact rating matters to your specification, ask us to confirm it against the current production drawing before you order.
Reinforcement, pressure class and temperature. SAE 100 R2 uses two wire braids and is rated to +100 °C; the spiral grade uses four plies of steel wire wrapped in alternating directions and is rated to +120 °C. At 1 inch bore the two grades carry 2400 PSI / 165 BAR and 5510 PSI / 380 BAR respectively.
Petroleum based hydraulic fluids. That is narrower than the braided SAE grades, which also cover water based fluid, fuel and lubricating oils. For water glycol, synthetic ester or any chemical service, send us the fluid specification and we will confirm suitability before quoting.
Standard export format is loose hose in coils, packed for sea freight from Nhava Sheva (JNPT) or Mundra Port. Crimped assemblies are made to order when bore, assembly length and end fitting details are supplied. Every consignment ships with commercial invoice, packing list, certificate of origin, bill of lading and test certificates.
Burst, impulse and dimensional testing is carried out in our own R&D laboratory, with all test equipment calibrated by NABL-accredited bodies. For a high cycle spiral product, impulse performance is the property that decides service life, and the test certificate for your batch ships with the consignment.
A four-spiral hose has a larger minimum bend radius than a braided hose of the same bore, and forcing it tighter at the ferrule is a common failure cause. Send us the bore and the routing constraint and our technical team will confirm the minimum bend radius for that size before you commit to a layout.
No. Pricing depends on bore, quantity, fitting requirement, Incoterm and destination port, so it is quoted on request rather than published. Send your requirement to mktg@flexihoseindia.com or WhatsApp +91 9251554066 and our export team returns an FOB or CIF quotation within 24 hours.
Yes. The spiral grade ships alongside R1, R2, R3 and R6 on one bill of lading, and industrial rubber, suction and discharge and stainless steel hoses can be added to the same container. LCL shipments can be arranged for trial orders.
