KRASS Cutting Nozzle №6 — size 6 nozzle for accurate steel cutting
The KRASS Cutting Nozzle №6 is a size 6 nozzle for manual and machine oxy-fuel cutters. REAL GAZ supplies it with the oxygen and fuel gases it needs, so the whole cutting set-up can be specified together.
A nozzle number describes the size of its orifices, which in turn decides the plate thickness range, gas consumption and the speed that can be reached.

Cut quality is judged against EN ISO 9013, and equipment safety against EN ISO 5172 and EN 730-1, suitable for industrial and training use.
🏭 Where KRASS №6 Cutting Nozzles Are Used
- 📐 Straight-line cutting — the nozzle gives a narrow kerf and square edges when travel speed is steady;
- 🔩 Bevel preparation — welders prepare V and K edges on plate before welding, saving machining time;
- 🎓 Technical training — colleges teach flame setting and cutting technique on a standard, easy-to-obtain nozzle size;
- 🛠️ Repair workshops — vehicle and machinery repairers remove damaged steel parts before fitting new sections.
💡 Why Choose REAL GAZ
- ✅ Defined size — a numbered nozzle makes it easy to document and repeat cutting settings;
- 🧪 Compatible gases — suitable for use with oxygen and the fuel gases commonly supplied for gas cutting;
- 🎯 Clear selection help — we relate nozzle size to plate thickness and torch type before you order;
- 🔒 Safe supply chain — cylinders, regulators and flashback arrestors can be supplied together;
- 📄 Certificate of Analysis (CoA) — supplied with every gas order.
🔬 Quality Control & Safety
- orifice size and finish inspection;
- torch fit verification;
- cutting oxygen purity analysis;
- leak testing and pressure integrity checks.
Gas cylinders supplied with the equipment comply with ADR / UN transport rules and relevant EN/ISO standards.
🛠️ Using Size 6 Nozzles Correctly
- Choose the nozzle by plate thickness, not by habit: oversized nozzles waste gas and undersized ones stall mid-cut.
- Light the preheat flames first, adjust to neutral, then open the cutting oxygen lever smoothly once the steel is bright red.
- Inspect the nozzle seat every shift; a scored seat is a leading cause of backfire and internal leaks.
📏 Reading Nozzle Numbers
Nozzle numbering is a convenient shorthand: a higher number generally means larger orifices, more oxygen flow and the ability to cut thicker steel, but each torch maker publishes its own chart. A №6 nozzle sits in the middle-to-upper part of many ranges, which makes it a frequent choice for general fabrication rather than light sheet or very heavy plate. Record the pressures, speed and result of a good cut and keep them at the workstation, so any operator can repeat it. If the edge shows heavy top rounding the preheat is too strong; if the cut drags and leaves slag on the underside, speed or oxygen pressure is likely too low. Small adjustments often fix both.
