Alumina Nozzle 1/2 In No 8 Pack of 10
Miller Weldcraft 57N74 alumina nozzles protect the TIG torch tip and shape shielding gas flow during welding tasks. Each nozzle is made from alumina ceramic for electrical insulation and heat resistance. The pack contains ten nozzles for workshop or field use.
Suited for TIG welders using compatible Miller
These size 8 nozzles fit torches that accept a 1/2 inch alumina tip. Welders who need a different bore size or a thread pattern not matching this model should select another part number.
Bore size 1/2 inch determines gas coverage
The 1/2 inch internal diameter sets the shielding gas envelope around the tungsten electrode. Match this dimension to your torch series and joint access requirements before ordering.
