LOCKNLUBE® GB17 Clearout Clogged Grease Fitting
The Original Grease Buster® is the most rugged version of his products, fit for heavy use and compatible with the pneumatic piston. The Grease Buster's piston, included with the product is hollow and should be filled with a liquid (not aerosol) penetrating oil. Seat the piston in the grease buster, attach the coupler to your zerk fitting and tap the piston with a hammer. This forces the penetrating oil into the fitting and loosens it for regular greasing. For customers with a pneumatic hammer, they might prefer using the pneumatic piston instead of the standard piston.
