KRASS Cutting Nozzle №1 — fine, controlled flame cutting for thin steel
KRASS Cutting Nozzle №1 from REAL GAZ is the smallest numbered size in the series, built for operators who cut thin plate, sheet and light profiles where a narrow kerf and a small heat-affected zone matter more than raw cutting depth.
Each nozzle is machined from copper and brass alloys, with a clean bore and a smooth cutting-oxygen channel so the jet stays straight and the preheat flame burns evenly around it.

REAL GAZ supplies this equipment with reference to EN ISO 5172, ISO 9012 and EN ISO 9013, suitable for workshop and site cutting with oxygen and acetylene or propane.
🏭 Where KRASS №1 Cutting Nozzles Are Used
- ⚙️ Sheet-metal workshops — trimming thin carbon-steel sheet and cutting gussets, brackets and base plates where a small nozzle keeps distortion low;
- 🔧 Maintenance and repair — removing damaged panels, bolts and light structural elements during equipment servicing, with a flame that is easy to control by hand;
- 🚛 Vehicle and trailer fabrication — cutting chassis plates, mudguards and tank covers to size before welding, with minimal slag on the underside;
- 🏗️ Site dismantling — cutting thin-walled pipes, ducts and cladding on demolition projects where larger nozzles would waste gas.
💡 Why Choose REAL GAZ
- ✅ Correct size for thin metal — the №1 bore delivers a compact cutting-oxygen jet so thin steel is parted cleanly instead of being blown away;
- 🧪 Consistent flame — uniform preheat orifices give a stable, even flame ring that lights quickly and does not pop at low settings;
- 🎯 Easy torch fit — dimensions follow the torch manufacturer seat geometry, so the nozzle seals without extra washers or force;
- 🔒 Matched supply of gases — oxygen and fuel gases for your torch can be ordered from the same supplier, with the same delivery schedule;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- dimensional checks of seat, thread and bore;
- visual inspection of the preheat orifices for burrs;
- flame test on oxygen and fuel gas before dispatch;
- protective packing against dents and thread damage.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📏 Selecting the Right Size
- Numbered nozzle sizes correspond to the metal thickness range given in the torch maker table, so always check that table first;
- Use №1 for thin plate and step up to a larger number when the cut becomes slow or the edge begins to melt;
- Keep oxygen and fuel pressures within the torch instructions rather than raising pressure to compensate for a worn nozzle.
