Choosing a hydraulic hose for a Saudi site is a question of four numbers and one environment. The numbers are inside diameter, working pressure, fluid temperature and minimum bend radius. The environment is heat, sun and sand. Raipur Hydraulics supplies hose cut and assembled to your positions, and bulk hose with matched fittings for workshops that crimp locally. The hose make and standard are stated in every quotation; we build assemblies and make fittings in-house, and bulk hose is sourced from established hose manufacturers.
Hose families we supply
| Family | Construction | Typical use on Saudi equipment |
|---|---|---|
| SAE 100R1 / EN 853 1SN | One steel-wire braid | Return and pilot lines, low-pressure attachments |
| SAE 100R2 / EN 853 2SN | Two steel-wire braids | General machine hydraulics, cranes, plant equipment |
| EN 856 4SP | Four steel-wire spirals | High-pressure lines on loaders and excavators |
| EN 856 4SH | Four steel-wire spiral layers; size and rating confirmed from product data | Main pump and boom circuits on large excavators and shovels |
| SAE 100R13 / R15 | Multi-spiral, constant pressure class | High-impulse circuits on haul trucks, dozers and drills |
| Thermoplastic | Polymer core, fibre or wire reinforcement | Light hydraulic and lubrication lines where specified |
Sizes are quoted by dash size, inch or millimetre. Metric and inch fittings are both accepted.
Why the cover matters more in the Kingdom
The reinforcement holds the pressure; the cover protects the reinforcement. On Saudi sites the cover is under constant attack. Ultraviolet light and ozone harden rubber and start fine surface cracks on hoses that sit in the sun on parked machines. Wind-blown sand acts like abrasive paper wherever a hose touches another hose or a steel edge. Once the cover is through, moisture and grit reach the wire, and the hose fails long before its pressure life.
For that reason we treat cover choice as part of the specification, not an afterthought:
- Abrasion-resistant covers for positions that move against each other, such as boom bundles and loader articulation
- UV- and ozone-resistant covers for lines that spend long periods in direct sun
- Fire-resistant (MSHA-type) cover hose, available on request for underground or hot-zone positions. RHPL does not claim an MSHA approval; send your site specification.
- Spiral guards and textile sleeves where contact cannot be designed out
Temperature: rating versus reality
Review temperature limits for the fluid and ambient exposure against the manufacturer's product data. In a Saudi summer, three things push the real temperature up: high ambient air, radiant heat from steel and engine bays, and oil that runs hotter when coolers work against hot air. We ask for the expected oil temperature and the hottest part of the routing, then choose a hose with a margin. Where a hose has to pass close to a turbocharger or exhaust, review the routing and any protective sleeve against the actual heat exposure; a higher temperature rating alone does not resolve every routing hazard.
Bulk hose for Saudi workshops and hose houses
Workshops and hose houses in the Kingdom can order bulk hose in matched families with ferrules and fittings, so that crimp data stays consistent. We state the hose make, standard and crimp specification in the quotation. Bulk supply is bought and resold in your own name; RHPL holds no stock in Saudi Arabia. Hose houses interested in a regular arrangement can read Dealer & Stockist or Local Supply Partners.
Arabic hose terms
For an enquiry in Arabic, you can use "خرطوم هيدروليكي" or the Gulf term "لي هيدروليك" to identify a hydraulic hose. Our Arabic glossary matches common Arabic words to the English terms used in quotations: hose (خرطوم / لي), fitting (وصلة), ferrule (جلبة), crimping (كبس). Standard notation such as BSP, JIC, ORFS, 4SH, R13 and SAE stays in Latin letters in both languages.
Select the construction from the machine specification, fluid, working pressure, temperature and minimum bend radius. Send the old layline, machine model and hose position for review; no family is selected from machine size alone.
Can you supply hose that resists sun and sand better? Yes. We select abrasion- and UV-resistant covers and add spiral guards or sleeves where hoses rub. The cover type is written into the quotation.
Do you offer fire-resistant hose? Fire-resistant (MSHA-type) cover hose is available on request. RHPL does not claim an MSHA approval; send your site specification so we can confirm the hose.
Can I buy hose by the reel for my workshop? Yes. Bulk hose is supplied with matched ferrules and fittings and the crimp specification. You buy and resell it in your own name.
