COLLECTION 01 / WELDING
OXY-ACETYLENE WELDING NOZZLES
Oxy-acetylene welding nozzles in the British numbering system run No. 1 to No. 25 - the higher the number, the larger the orifice and the heavier the duty it is sized for. They screw onto standard oxy-fuel torch heads and are sold as single numbers or as sets; sometimes searched for as gas welding nozzles, these are fusion-welding and heating nozzles, not brazing nozzles.
Match the number stamped on your old nozzle, then confirm against the size table on the product page. If the stamp is worn, measure the orifice - or send us a photo of the old nozzle and we will identify it.

The higher the number, the larger the orifice and the heavier the duty. Orifice and flow figures for the numbers you use are confirmed on request - better the right figure than a printed guess. Check local gas-appliance rules before fitting replacement oxy-fuel nozzles.
PRODUCT GRID - the numbers above are the sizing reference; oxy-fuel nozzles are matched on request while we build the stock list. Send the stamp on your old nozzle and we confirm the number.
