Saudi fleets and plants are built from machines that come from everywhere, and so do their threads. A Japanese excavator, a European crusher, an American haul truck and a Chinese loader can share one workshop, and each brings its own fitting families. Raipur Hydraulics machines hose fittings and adaptors on two in-house CNCs in Raipur, India, so we can supply standard families in volume and consider non-standard adaptors to a confirmed drawing. Saudi hose houses and workshops can request quotations for both.
Fitting families
| Family | Seal | Where you find it |
|---|---|---|
| BSPP (parallel) | Cone seat or suitable sealing element, depending on fitting design | Confirm the actual port |
| BSPT (taper) | Sealing on the tapered thread according to the fitting system | Confirm the actual port |
| JIC 37° | Metal-to-metal flare | North American machines, many mobile circuits |
| ORFS | O-ring face seal | High-pressure mobile machines; good against vibration leaks |
| Metric DIN (light and heavy series) | 24° cone, with or without O-ring | European machines, cranes, plant |
| NPT / NPTF | Tapered thread | Older equipment, air and water lines |
| SAE flange code 61 / 62 | O-ring flange face | Large-bore pump and boom lines on heavy machines |
| Staple-lock | O-ring with staple | Underground and some mining machines |
| Ferrules and inserts | Matched to hose family | For hose houses that crimp locally |
Adaptors and custom CNC work
The CNCs matter most when the standard catalogue runs out. Requirements we can review include adaptors between two thread families on a mixed fleet, long-reach or special-angle fittings for tight routing, replacement fittings for older machines whose parts are hard to find, and flange adaptors for large-bore lines. Send a drawing, a sample photo with measurements, or the two thread types to join, and we confirm dimensions before machining. Small batches to drawing are normal work for us.
Plating for the Gulf and Red Sea coasts
Plants on the coast at Jubail, Dammam, Ras Al-Khair, Yanbu and Rabigh face humid, salt-laden air for much of the year. Plain zinc plating corrodes there faster than inland, and corroded fittings are hard to remove and can leak at the seal. Zinc-nickel plated and stainless-steel fittings can be offered for these positions. We recommend them for externally exposed lines on coastal plants, cranes and loading equipment, and for any position where a fitting has to be removed and refitted many times. The plating or material is stated in the quotation.
Sand, dust and seal choice
Inland, the enemy is dust rather than salt. Every time a line is opened, sand can enter the fitting and travel into valves and pumps. Three practical measures help: choose O-ring face seals where the machine allows, only with a compatible port and specification; every sealing surface must be clean; cap and plug every open end during maintenance; and keep spare fittings in sealed packaging until they are fitted. Ask for capped ends on assemblies and fittings in your enquiry, and we confirm it in the quotation. O-ring material, for example NBR or FKM, is chosen for the fluid and operating temperature.
Supplying Saudi hose houses
If your Saudi workshop crimps hoses locally, you can request fittings and ferrules matched to the hose family and approved crimp data. We can quote a fittings programme matched to the hose you already use, with ferrules, inserts, adaptors and a dimension sheet. You buy and resell in your own name; RHPL holds no stock in Saudi Arabia. If you supply mines or major projects, read Local Supply Partners.
FAQs
Can you make an adaptor between two different thread types?
Yes. Tell us the two thread or flange types, or send a drawing or a photo with measurements. We confirm the dimensions before machining.
Do you offer corrosion-resistant fittings for coastal plants?
Yes. Zinc-nickel plated and stainless-steel fittings can be offered. The plating or material is confirmed in the quotation.
Can I order fittings and ferrules without hose?
Yes. Hose houses and workshops can request fittings, ferrules and adaptors separately, matched to the hose family and confirmed crimp specification.
How do I identify a fitting I cannot read?
Photograph it beside a ruler, measure the thread outside diameter and count threads per inch or measure the pitch, and note the seal shape. We confirm the family from that.
