Block Ribbon Specialty Nozzle

Check Valve 101 - Needed and Sold Separately. These nozzles are for our professional line of hot melt glue guns. Nozzles fit our glue guns (100 Watt or higher). 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." If you are unsure whether these nozzles will fit your glue gun, please contact us.
