Hand drawn electrolytic, tough pitch copper used in one-piece nozzles – withstands heat and wear – outlasts any copper alloy nozzle~One-piece nozzle has triple swaged interior – gas passages are mirror smooth with internal angles rounded for non-turbulent, more efficient gas flow – clean, smooth cuts with minimal kerf~Preheat ports are closely spaced around cutting orifice for greater concentration of preheat flames~Hard drawn, electrolytic, tough pitch copper used in one-piece nozzles – withstands heat and wear – outlasts any copper alloy nozzle~One-piece nozzle has triple swaged interior – gas passages are mirror smooth with internal angles rounded for non-turbulent, more efficient gas flow – clean, smooth cuts with minimal kerf~Preheat ports are closely spaced around cutting orifice for greater concentration of preheat flames~Long, parallel preheat passages – permit re-dressing nozzle without affecting performance~One-piece nozzle is a single piece of solid copper – provides maximum cooling – recommended always for acetylene, and for other fuel gases when heat exposure is unusually severe~Two-piece nozzles – recommended for high efficiency with fuel gases other than acetylene – solid copper, heavy-wall external sleeve and brass internal sections can be ordered separately to minimize replacement cost~Conical seats – instant aligning provides tight seal, prevents leaks around nozzle nut
