Brass and Copper Nozzle PNM KRASS №6 — copper and brass construction for stable cutting flames
The Brass and Copper Nozzle PNM KRASS №6 from REAL GAZ combines two metals chosen for gas cutting: copper for fast heat conduction and brass for strength and machinability of threads and seats.
This combination helps the nozzle tolerate repeated heating cycles, while a smooth internal bore keeps the cutting oxygen jet narrow and steady.

Materials and torch interfaces follow the principles of ISO 9539 for materials in gas welding equipment and EN ISO 5172, suitable for fabrication and maintenance use.
🏭 Where PNM KRASS №6 Nozzles Are Used
- 🔥 Heavy section cutting — copper’s thermal conductivity carries heat away from the nozzle face during long cuts in thick steel;
- 🏭 Production lines — repeatable bore geometry gives consistent kerf width from one shift to the next;
- 🔧 Maintenance departments — plant technicians use the nozzle for removing seized bolts, flanges and damaged brackets;
- ⛏️ Mining and quarry service — field crews cut worn liners and structural parts where portable oxy-fuel kit is the practical choice.
💡 Why Choose REAL GAZ
- ✅ Two-metal design — copper and brass are each used where their properties help most;
- 🧪 Clean bore finish — smooth passages reduce turbulence in the oxygen stream and help prevent spatter build-up;
- 🎯 Thread accuracy — precision-cut threads and sealing faces reduce gas leakage at the torch head;
- 🔒 Long working life — with correct handling and cleaning the nozzle withstands many cutting hours;
- 📄 Certificate of Analysis (CoA) — supplied with every gas order.
🔬 Quality Control & Safety
- material and dimensional inspection;
- bore cleanliness and burr check;
- thread and sealing face examination;
- leak testing of supplied gas cylinders and fittings.
Gas cylinders supplied with the equipment comply with ADR / UN transport rules and relevant EN/ISO standards.
🛠️ Care of Copper and Brass Nozzles
- Clean the bore only with correctly sized tip cleaners; a drill bit or wire of the wrong size will widen the orifice and spoil the flame.
- Do not drop or strike the nozzle face on steel plate, because copper is soft and a damaged face disturbs the flame pattern.
- Let the nozzle cool in air after use; quenching in water can stress the metal and loosen the seat.
🔬 Why the Metals Matter
Copper conducts heat roughly ten times better than mild steel, so it draws heat from the nozzle face and spreads it along the body instead of letting it concentrate at the orifice. Brass, an alloy of copper and zinc, is harder and machines cleanly, which suits the fine threads and conical seat that must seal against the torch head. Together they resist the thermal shock of lighting, cutting and cooling hundreds of times. Operators should avoid copper-bearing cleaning compounds near acetylene piping, and should never use tools harder than the nozzle to scrape the face. A nozzle kept clean and undamaged will deliver the flame pattern it was machined to produce for far longer.
