All of our glue nozzles are made to last, with basic maintenance. To get the most out of your nozzles, keep the roller immersed in the water reservoir between gluings during your glue work. After the job is completed, be sure to flush the nozzle of any remaining glue with water- use our Tap Adapter which works with all of our nozzles for the best results. Because the roller is textured, wiping down with a rag or brush will ensure no excess glue dries on the roller. For a full description of how to get the most out of your Pizzi glue system, consult our maintenance guide.
