Applications
HIFLUX valves, fittings and tubing selected for the specific demands of each application — from 700 bar hydrogen refuelling to 150,000 psi research rigs and 1200°F steam service. Choose your industry below to see the duties, what to specify and the components we recommend.
Hydrogen refuelling is the most demanding gas-handling duty in commercial service. A 700 bar dispensing circuit combines extreme pressure, hard cycling, pre-cooling to −40°C, and the smallest molecule in industry — and every component in it has to be qualified for all four at once.

Wellhead instrumentation lives with high static pressure, sour media, temperature swings and the certainty that every isolation point will be tested by an inspector at some stage. Components have to hold, and they have to be demonstrably traceable when someone asks.

Test rigs are rebuilt constantly. A pressure-cycling bench, a burst test cell or a materials rig may be reconfigured between every run, and the connection system has to survive being broken and remade dozens of times without degrading. That requirement rules out most fitting types before pressure is even considered.

In chemical and refining service the pressure rating is rarely the hard part. Material compatibility is. A component that holds 20,000 psi indefinitely on nitrogen can fail in weeks on the wrong media, and the selection decision belongs at enquiry rather than after commissioning.

Power plant instrumentation runs hot. Steam sampling lines, drum level measurement and turbine monitoring all put small-bore tube and its connections at temperatures that rule out elastomeric sealing entirely — and that is where metal-to-metal connections earn their place.

FAQ
Yes. HIFLUX makes valves and fittings for hydrogen refuelling stations, including KS-certified H70 manual valves (certificate KGS-23-0003), in cold-formed 316 stainless steel with metal-to-metal cone and thread connections.
A metal-to-metal seal made by a coned tube end seated in a matching cone in the fitting, held by a gland and collar on a left-hand thread. It needs no elastomer, holds to 150,000 psi and can be broken and remade, which is why test rigs and high-temperature lines use it.
316 stainless steel is standard. Hastelloy, Inconel 600/625/825, Nickel 200 and titanium are available where the media or temperature requires them. Send us the media and we will advise.
Yes. Manufacturer material certification, traceable to the batch, is available with your order. Tell us the documents you need when you enquire.
The working pressure, temperature range, media, tube size and connection type, and the quantity. A part number or bill of materials is ideal if you have one.
