Hiflux UK is the exclusive UK and EU distributor for HIFLUX Co., Ltd of Daejeon, South Korea — a manufacturer of ultra high-pressure valves, fittings and tubing since 2010, and a designated Hydrogen Specialist Company under Korea's Ministry of Trade, Industry and Energy.
We hold UK stock, handle EU-facing supply, and provide the technical and documentation support a UK or EU project needs. Every series, every certificate and every batch is genuine HIFLUX product, traceable back to the manufacturer.
If you are sourcing HIFLUX components in the UK or EU, source them from the authorised distributor. Grey-market product carries no traceable material certification — and on a 150,000 psi line, that documentation is the whole point.
