Canister System Tips & Tricks Series, Part 3: Gun Leaking or Won’t Shut Off
The canister system is one of the simplest and most efficient adhesive system to use, but sometimes mistakes happen, and things go wrong. This article is part of a series outlining common industry mistakes, and what to do to ensure the same doesn’t happen to you!
Is your spray gun leaking, or refusing to shut off? This could be caused by a loose nut in front of the adjusting nut, or from the valve seat being loose or missing.
Sometimes the nut in front of the adjusting nut can loosen and slip forward. If this is the case, just twist it back to tighten.
If the valve seat (the flat piece of metal in between the tip and the gun) is the problem, shut the canister valve off and empty the hose. Remove the tip and the nut from the front of the gun, and tighten or replace the valve seat. Put the tip back on, tighten the nut, turn the canister valve on, and you should be good to go!
