Grease Buster grease flushing tool, Made in USA black coupler — penetrating fluid & hydraulic pressure to clear dried grease

Grease Buster® is a U.S.-made mechanical flushing tool that forces penetrating fluid and hydraulic pressure through fittings, pins, shafts, bushings, and joints to remove old, dried grease.

Built by LockNLube in New Hampshire, this product restores lubrication passages by combining a penetrating oil with pressurized flushing action so you can clean stuck or contaminated grease locations without immediate part replacement. It’s designed for maintenance shops, fleet technicians, and hands-on owners who want to extend component life, reduce downtime, and avoid unnecessary bearing swaps.

How does the Grease Buster® remove hardened grease from fittings?

The Grease Buster® uses a two-step approach: a penetrating fluid to break down dried grease and hydraulic pressure to force contaminants out of the lubrication channels. This flushes residual grease, dirt, and moisture from the interior of fittings and joints where hand-cleaning can’t reach.

• Penetrating oil dissolves old, compacted grease.
• Hydraulic pressure pushes dissolved contaminants out of pins, shafts, and bushings.
• Available coupler connects to standard grease fittings for controlled flushing.

What parts and problems can I use it on?

Grease Buster® is intended for grease fittings, pins, shafts, bushings, joints, and similar lubrication points commonly found on agricultural, construction, and industrial equipment. It’s most effective where old or contaminated grease impedes movement or prevents fresh lubricant from reaching internal surfaces.

• Suitable for zerks, grease nipples, and common grease fittings.
• Works on pivot pins, bushings, bearings, and linkages.
• Helps remove moisture and debris that causes premature wear.

How will using the Grease Buster® reduce downtime and cost?

By clearing blocked lubrication channels and removing abrasive contaminants, the unit restores proper grease flow so components can be lubricated effectively without immediate replacement. That saves labor and parts costs and can extend intervals between major repairs.

• Flushes contaminants so fresh grease reaches bearing surfaces.
• Avoids many premature bearing replacements and associated labor.
• Makes routine maintenance faster and more reliable.

What should I expect in the box and any packaging notes?

The Grease Buster® ships with the flushing unit and a coupler; packaging may feature the older silver coupler artwork while physical units include the new black-style coupler. All units are manufactured in the USA by LockNLube in New Hampshire.

• Unit includes penetrating-fluid delivery and pressure application components.
• New black coupler included with current production units.
• Made in the USA — assembled and quality-checked by LockNLube.

Who is this for? Maintenance technicians, fleet managers, equipment owners, and DIY mechanics who service agricultural, construction, or industrial machinery will benefit most. If you regularly encounter seized fittings, contaminated grease, or components that don’t accept fresh lubricant, the Grease Buster® provides a cost-effective way to restore lubrication paths and delay expensive replacements.
