Save time and protect your equipment! The Pocket Model Grease Joint Rejuvenator® uses light-viscosity oil and pressure to open clogged joints and fittings in minutes - no heat, disassembly, or hours of work are necessary. The Grease Joint Rejuvenator® cleans the joint by forcing any light-viscosity oil in through the fitting. Just fill the tool's body with oil, connect to the Zerk fitting, and gently tap repeatedly to pressurize the oil and force it into the joint, until the new oil has fully displaced the old, hardened grease. Like magic, all of a sudden you will feel the joint open and the joint or pin can then be greased. A must-have tool for excavators, dozers, loaders, backhoes, tractors, implements, shafts, or bearings.

Instantly opens clogged grease joints 2.5X more pressure than the professional model Especially handy for small equipment - fits in your pocket Versatile use across farm, construction, lawn care, excavation, manufacturing, machine shops, well-drilling rigs, cars, trailers, and marine drivetrains Lubricates and clears blockages in bearings, control arms, king pins, piston arms, shafts, bushings, and more Backed by a manufacturer lifetime warranty Patented design
