Who we are
Hiflux UK supplies Hiflux high-pressure flow-control products to engineers, procurement teams, system designers and industrial organisations across the United Kingdom.
We are a distributor, not a manufacturer. The products are made by HIFLUX Co., Ltd., a South Korean manufacturer of high-pressure valves, fittings and piping materials established in 2010. Our role is to make that range accessible here — with the technical information needed to specify correctly first time, and a UK contact who stays with the enquiry through to delivery.
Working pressures
Published working pressures run from instrumentation level up to 150,000 psi in selected fitting, tubing and needle-valve families. Confirm any rating against the relevant product documentation.
Why work with Hiflux UK
Most of the work happens before the order. Engineers come to us with a pressure, a medium and a port type; buyers come to us with a part number that needs pricing, or a bill of materials that needs checking.
A UK contact who answers the technical question rather than routing it offshore, in UK working hours with no time-zone gap in the middle of a technical conversation.
Matching an application to a catalogue number: pressure rating, orifice, stem type, port type, material.
Catalogues, dimensional data, port types and material specifications on request.
A second pair of eyes before the order goes in: we check part numbers, flag mismatches, and identify where another configuration suits the duty better.
Written and itemised, against your specification.
Placing and tracking the order, with one named UK contact from enquiry to delivery and afterwards.
The manufacturer
Hiflux products are manufactured by HIFLUX Co., Ltd., established in 2010 in Daejeon, Republic of Korea, and based since 2018 at a headquarters and factory in Daedeok Techno Valley.
The company holds patents covering a double-sealed check valve, a high-pressure valve, a high-temperature/high-pressure valve and valves incorporating stem carriers, and supplies domestic OEM customers alongside overseas waterjet equipment manufacturers. Its hydrogen line includes manual valves certified to KS standards by the Korea Gas Safety Corporation; in 2024 it was designated a Hydrogen Specialist Company by South Korea's Ministry of Trade, Industry and Energy.
Design authority, manufacturing and product certification rest with HIFLUX Co., Ltd. Hiflux UK distributes those products in the United Kingdom.

Mission and values
“Our mission is to give UK engineers and buyers straightforward access to Hiflux high-pressure products, with the information and documentation needed to specify and buy them with confidence — judged on the quality of our answers, not the size of our catalogue.”
We quote what the documentation supports. If we do not know a figure, we find it or say so.
A real contact, reachable in UK hours.
Genuine Hiflux product, traceable to the manufacturer.
Clear lead times and clear limits. We would rather decline an enquiry than push a product into the wrong duty.
Most of our value shows up on the second project, not the first.
Product range
Needle, ball, relief, safety, bleed, double block and bleed, high-temperature, control and air-operated, in 316 stainless steel, Inconel and Monel alloys.

High-pressure check valves and line filters, including a patented double-sealed design.
Manifold blocks, with sizes, specifications and port-type combinations available to order.
Regulators, back-pressure regulators, air-operated BPRs, safety heads and rupture discs, gauges and thermocouples.

Industries
Suitability for a specific duty must always be confirmed against the product documentation and your own design requirements.
High-pressure tubing and fittings.
Wellhead gauge, bleed and double block and bleed valves for pressure monitoring and testing, chemical injection, sampling and drain-line isolation.
Tubing and fittings across the full pressure range.
The manufacturer supplies overseas waterjet equipment makers on an OEM basis.
Valves and fittings developed for refuelling stations, including H70 applications.
Quality
Product quality, testing and manufacturing certification are the responsibility of HIFLUX Co., Ltd. and do not transfer automatically to Hiflux UK. Our role is to obtain the documentation UK customers need for design files, supplier approvals and site records. Each certificate covers only the scope written on it.
Experience and expertise
High-pressure specification is a conversation, not a catalogue lookup. Cone-and-thread connection selection, material choice for the medium, orifice and Cv sizing, port-type conversion between standards — these are the questions we expect.
