Brass and Copper Nozzle PNM KRASS №3 — materials chosen for heat and durability
The Brass and Copper Nozzle PNM KRASS №3 combines two metals for good reason: copper conducts heat away from the hot nozzle tip quickly, while brass offers a machinable, wear-resistant material for threads and seats.
This combination helps the nozzle survive repeated heating and cooling, so REAL GAZ recommends it for users who cut every day.

Material selection follows the principles of ISO 9539 for gas welding equipment, with EN ISO 5172 for torch performance, for continuous and demanding use.
Oxygen-service components must be clean, so nozzles are handled and packed free of oil and grease. Brass and copper alloys are widely favoured for such parts because they are far less prone to ignition than steel when exposed to high-pressure oxygen, and they machine to a good finish.
🏭 Why the Materials Matter
- 🌡️ Heat dissipation — copper has high thermal conductivity, which keeps the tip face cooler and reduces cracking and erosion;
- 🔩 Threads and seats — brass is easily machined to precise dimensions and resists galling when the nozzle is tightened;
- 💨 Oxygen service — both metals are widely used in oxygen equipment because they do not readily ignite under normal working conditions;
- ♻️ Longer service life — a well-chosen material pair reduces replacement frequency and operating cost.
💡 Why Choose REAL GAZ
- ✅ Resistance to thermal fatigue — repeated flame cycles do less damage to a well-conducting copper tip;
- 🧪 Accurate machining — brass fittings hold tight tolerances, so the nozzle seats cleanly and does not leak;
- 🎯 Practical size — №3 serves a broad band of plate thicknesses for general cutting;
- 🔒 Clear specification — our team can describe materials and dimensions so you can specify spares precisely;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- incoming checks on alloy stock;
- machining tolerance control;
- inspection for porosity and surface defects;
- flame test and leak check.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
🧼 Looking After Copper and Brass Nozzles
- Avoid striking the tip against the work, because copper is soft and deforms easily;
- Clean with proper tip cleaners and never enlarge the orifices;
- Keep nozzles in a dry box away from oil, since contamination is a hazard in oxygen service.
