RFS was established in 2016 in Singapore as a subsidiary of Chuan Kok Hardware (founded 1982). As our own brand, RFS holds full control over sourcing, testing, warehousing and marketing — its products are made by manufacturers held to our specification, so the product standard stays consistent from factory to warehouse, and a repeat order always matches the first.
Hydraulic SAE J518 flanges, plus split and blind versions, and our square and LSA square flanges. Five of the twenty catalogues are flanges alone.
Compression, double ferrule, JIC, forged pipe and pipe adapter fittings — the five connection types that cover most hydraulic tube work.
SS316 needle valves 6000 PSI in F×F and M×F port arrangements, for throttling and fine flow control.
Walform tube, the Walform machines that cold-form the end, and the Walform seals that go with them. A formed end instead of a cut ring — fewer leak paths on a high pressure run.
Forged fittings for higher pressure pipe work, where a threaded or welded joint has to carry real load.
O-rings, GS Hydro bonded seals, Dowty seals and the GS Hydro retain ring — the parts that decide whether an otherwise correct assembly actually seals.
| What you need | How RFS answers it |
|---|---|
| One supplier across the whole joint | Six families under one brand — the flange, the fitting, the valve and the seal arrive in one order. |
| A specification that does not drift | Manufacturers held to our specification, so a repeat order matches the first. |
| Parts this week, not this quarter | Stock in Singapore & Malaysia — goods leave the warehouse within 24 hours of your PO. |
| No lock-in to a house pattern | SAE J518 flanges and recognised thread forms — RFS swaps in, and swaps out. |

RFS stands for Reliable Fluids System — our own line, and the widest one we publish: 20 catalogues across six product families. Established in 2016 in Singapore as a subsidiary of Chuan Kok Hardware, founded in 1982.
Manufacturers we hold to our specification. The specification does not drift between orders, the parts carry the RFS label, and quality is verified in-house on our own equipment before they ship.
Yes — that is the point of building on standards, not house patterns. The flanges are SAE J518 and the fittings use recognised thread forms, so RFS swaps into an existing design — and swaps out again with no lock-in.
Every RFS product line is verified on our own equipment rather than taken on trust from a supplier certificate. The result: a repeat order matches the first one, and our client retention is 92%.
RFS is what we reach for when we control the specification; the named brands we distribute are there when your specification names them.
No minimum order. Order what you need — from one piece to a container — at prices that stay competitive thanks to our long-standing relationships with trusted manufacturers.
Yes — 2,320+ line items are held as ready stock in our regional warehouses in Singapore and Malaysia. Goods leave the warehouse within 24 hours of your PO, with the delivery schedule to your city confirmed in the quotation.

Yes — material test certificates (MTC) and authenticity documents are available on request. Because RFS is our own brand, the supply chain and documentation are fully under our control.
