🏭 Where Oxygen Regulators Are Used
- ⚙️ Oxygen–fuel cutting — the regulator holds a stable oxygen pressure at the torch so that the preheat flame and cutting jet stay consistent along the whole cut;
- 🔬 Brazing and soldering — fine control of low outlet pressure helps technicians set a clean, neutral flame on copper pipework and fittings;
- 🏥 Metal fabrication yards — steel service centres and shipyards fit the regulator to cylinders and manifold tails for daily cutting lines;
- 🚀 Process oxygen enrichment — small furnaces and burners use a controlled oxygen feed to raise flame temperature and improve combustion efficiency.

📦 Fitting and Handling Notes
Never apply oil, grease or PTFE tape containing hydrocarbons to an oxygen fitting. Open the cylinder valve slowly with the regulator adjusting screw released, and stand to the side of the gauge face. Keep unused regulators in a sealed bag, away from dust and workshop oils.
Please ask us for the safety data sheet and operating guidance for oxygen equipment, and share them with every operator who will use the regulator on your site.
