Our pneumatic piston replaces the included Grease Buster® piston to take advantage of the added force and vibration of an air hammer. Double O-ring setup for even better performance and durability.

PROPER USE

The Pneumatic Piston replaces the standard piston in your Shop Size Grease Buster. It is compatible with pneumatic hammers and uses the percussion and vibration of the hammer to effectively work the penetrating oil into a clogged fitting.

The small and rapid impact from a pneumatic hammer is more effective than blows from a regular hammer to incorporate penetrating oil from the Grease Buster into the clogged fitting. The Grease Buster works by dissolving the clog, not blasting it out of the way. A pneumatic hammer aids in this process.
