ESAB 639607 NOZZLE 1566HS FG INT 6IN

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. 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.
