Cutting Nozzle HP 337

CUTTING NOZZLE HP 337 — a practical nozzle for everyday steel cutting

The Cutting Nozzle HP 337 is a consumable for oxy-fuel cutters, and REAL GAZ offers it as part of a complete gas cutting supply rather than as a loose part.
Nozzles are consumables, so having the correct model in stock and the right gas in the cylinder rack is what keeps a workshop productive.

REAL GAZ follows EN ISO 5172, EN ISO 2503 for regulators and ISO 5175-1 for flashback arrestors, suitable for fabrication and maintenance use.

🛠️ Using HP 337 Nozzles Safely

Purge hoses with each gas before lighting, and use a spark lighter rather than a cigarette lighter or matches.
Do not use grease or oil near oxygen fittings or on the nozzle thread; oxygen can ignite hydrocarbons violently.
Store spare nozzles in a clean box so the sealing surfaces are not scratched in a toolbox.

📋 Selecting Gas for the Nozzle

The nozzle is only one half of the process; the gases make the other half. Oxygen for cutting should be of high purity, since impurities lower cutting speed and roughen the kerf. Acetylene gives the hottest preheat flame and the quickest start, while propane is popular for thicker work because it burns with a larger outer cone and is economical on long cuts, provided the torch and nozzle are made for it. REAL GAZ can discuss both options with you and supply the cylinders, regulators and hose sets that suit your choice. If you operate several torches, we can also advise on cylinder frames or manifolds that keep supply steady during busy periods.
