The SpotON Nozzle Cleaner and Multi-Tool (27860) produces a strong, high pressure 50 PSI air blast to blow out and clear away any debris that may plug or clog your nozzles or nozzle tips. All you need to do is pull the plunger out, make sure the plunger is compressed, and release the 50 PSI compressed air by pressing the red nozzle. This nozzle maintenance tool also is a 4-in-1 tool that provides you with a much easier time servicing your nozzles or nozzle tips. It includes a brush, plastic pick, spanner wrench, and utility hook. The brush cleans dirt and debris out of nozzles. The plastic pick folds to clean clogged tips. The spanner wrench can tighten or loosen nozzle caps and check valves. The utility hook helps remove filters and disassemble nozzles.
