Grease Joint Rejuvenator Master Kit

Remove the piston and fill the tool with penetrating oil. Place the end of the tool on the grease fitting and tap the piston head with a hammer until it starts to move down into the tool body. The hydraulic pressure created by tapping on the piston forces the penetrating oil into the grease joint to the blockage. It loosens the old, hardened grease or dirt, flushes the blockage, and clears the way for new grease.
The Master Kit includes the
Professional Model Grease Joint Rejuvenator®,
the Pocket Model Grease Joint Rejuvenator®,
and the Flex Hose Extender and Coupler.
