Specialty nozzles for our professional line of hot melt glue guns. Nozzles fit our Heavy Duty Glue Guns (100 Watt or higher), Industrial Glue Guns, and Industrial Pneumatic Glue Guns. (These nozzles do not fit our Medium Duty or Cordless glue guns.)
Thread Size Information: The threads are 5/16-24 on the nozzle end (where the cap or extension nozzles fit). This is the same on the extension nozzles as the base of the extension is a cap nozzle. The portion that fits into the gun, as in the Nozzle Assembly, is a thread size of 7/16-20."
