Nagiee Grease Fitting Cleaning Tool with Replacement Tip & Spare O-Rings — Piston Solvent Pulse Cleaner for Zerk Fittings

Nagiee Grease Fitting Cleaning Tool uses solvent and hydraulic impact to clear clogged zerk fittings quickly, restoring lubrication flow for pins, shafts, bushings and joints.

Whether you maintain tractors, construction machinery, or automotive equipment, a blocked grease fitting can stop lubrication from reaching bearings and joints. The Nagiee tool is a compact piston-style cleaner that forces solvent through a clogged zerk (grease fitting) by tapping the piston with a grease hammer, breaking up dried grease and flushing debris so grease can pass freely again. It arrives with a replacement tip and spare O-rings so the kit stays serviceable through repeated use.

How does this tool clear a stubborn zerk fitting?

The device mixes penetrating solvent with hydraulic pressure generated by the piston. When you strike the piston with a hammer, a sudden burst of pressure forces the solvent through the fitting, dissolving and expelling hardened grease and contaminants. This mechanical pulse can reach blockages that manual syringes or grease guns cannot.

• Fill the piston with solvent (not included) and attach to the zerk.
• Strike the piston with a grease hammer to create a pressure pulse.
• Repeat as needed until the fitting allows grease flow.

What parts are included and how do I maintain the cleaner?

The kit includes the piston-style grease fitting cleaner, a replacement tip, and spare O-rings to maintain a reliable seal. Replace worn O-rings and the tip as needed to preserve pressure and prevent leaks; keeping a compatible solvent on hand speeds the process. Simple upkeep keeps the cleaner effective across many service tasks.

• One piston-style grease fitting cleaner body.
• Replacement metal tip for worn or damaged connections.
• Extra O-rings to restore seals and prevent solvent leakage.

Can this tool prevent equipment downtime and expensive repairs?

By restoring grease flow into bearings and joints, the Nagiee cleaner helps prevent accelerated wear from inadequate lubrication. Clearing blocked fittings is far less costly and time-consuming than replacing bearings, bushings, or other parts damaged by dry operation. Regular use as part of maintenance reduces the risk of unplanned breakdowns.

• Restores proper lubrication routes to bearings and joints.
• Reduces the likelihood of premature component failure.
• Speeds maintenance tasks to minimize downtime.

How should I use this safely and where is it most useful?

Use a recommended penetrating solvent and ensure the machine is de-energized before maintenance. The tool is intended for open zerk fittings; do not use on sealed bearings. It's ideal for heavy equipment, tractors, construction machines, and automotive service where zerks become blocked by dried grease or contaminants.

• Work with the equipment turned off and cooled, wearing eye protection.
• Do not use on sealed or non-serviceable bearings.
• Best for tractors, loaders, trailers, and workshop maintenance tasks.

Who is this for? The Nagiee Grease Fitting Cleaning Tool is built for mechanics, fleet technicians, farmers, and DIYers who perform routine lubrication maintenance. If you service heavy machinery, agricultural equipment, or vehicles and want a fast, affordable way to clear blocked zerks and protect bearings and joints, this compact kit—complete with a spare tip and O-rings—makes the job faster and more reliable without replacing parts prematurely.
