The Original Grease Buster® is the toughest tool on the market to open clogged grease fittings.
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 (sold separately) instead of the standard piston.
PROPER USE
The Original Grease Buster® is the answer to a problem that many people have lived with for a long time. Plugged-up grease fittings and bearings are a problem common in machinery. One greases a machine and the grease can dry out before the machine is used again. The tool consists of a heavy-duty adjustable hydraulic coupler, cylinder, and a piston with a knob.
Instructions: Remove the piston. Fill the cylinder by pouring in penetrating oil. Start the piston back into the cylinder. Place the tool onto the grease fitting and by tapping the piston, forcing the solvent into the fitting and or bearing. The key word is TAP. Using a lightweight hammer and small, rapid taps, work the penetrating oil into the fitting. You’re trying to dissolve the clog, not blast it out of the way. Repeat if necessary.

Amazing
Bought this grease buster for stubborn fittings on some equipment. Wow. Works amazingly. Quick shipping too


Pretty cool device
Worked like it said it did. Having a little trouble getting the grease fitting to stay on a couple of hard to reach zerks but other than that I'm happy overall

Great Expectations
I haven't had a chance to try it yet, but I had thought of the concept of this about the time it showed up. The concept is solid, and from the previous one I had (and lost), I have full confidence in the efficacy of this updated model.

Great Product
I had a couple of pins on a tractor loader that I recently purchased that would not take grease. I used the grease buster on them and it worked exactly as advertised. The whole process for two fittings took 20 minutes from opening the package to grease fittings that work as they should. Great product!
