The Original Grease Buster® (Clogged Grease Fitting Cleaner) – GB17-ANZ - GB19-ANZ - Service Kits
A patented tool for clearing clogged grease fittings (zerks) and restoring blocked grease pathways. The Grease Buster® consists of a machined steel cylinder and piston: fill the cylinder with penetrating oil, attach it to a stubborn Zerk fitting, and tap the piston with a hammer to force solvent into the blockage under high pressure. This dissolves hardened grease and frees up the lubrication passage, saving time and avoiding disassembly of equipment.
