QUESTIONS
How do I know which nozzle size I need?
Check the size stamped on your old nozzle or on the torch body, then match it in the compatibility chart. No stamp? Measure the orifice with a pin gauge, or send us your torch model - we match unlisted models for free.
What’s the difference between a brazing nozzle and a welding nozzle?
A brazing nozzle shapes a softer, broader flame that heats the joint and lets the filler flow without melting the base metal; a welding nozzle concentrates heat for fusion welding. The two are sized differently, so don’t swap them by guesswork.
Will these fit my EN417 butane torch?
Nozzles marked EN417 fit blowtorches that take the standard EN417 threaded butane cartridge - Campingaz CV270, CV300, CV470 and equivalent own-brand cartridges across Europe.
Do you supply nozzles in sets?
Yes. A set of the most-used sizes is the most popular choice for workshops - see the brazing and oxy-acetylene welding sets in the product grid.
