The Original Grease Buster® (Clogged Grease Fitting Cleaner) – GB17-ANZ / GB17-ANZ - Product Application

A patented tool for clearing clogged grease fittings (zerks) and restoring blocked grease pathways. The Grease Buster® consists of a machined steel cylinder and piston: fill the cylinder with penetrating oil, attach it to a stubborn Zerk fitting, and tap the piston with a hammer to force solvent into the blockage under high pressure. This dissolves hardened grease and frees up the lubrication passage, saving time and avoiding disassembly of equipment.


  • Purpose
    • Used to clear grease fittings that will not accept grease due to internal blockage
    • Restores grease flow in clogged or neglected lubrication points
  • Typical Users
    • Farmers
    • Heavy equipment operators
    • Industrial maintenance technicians
    • Mechanics working on older or poorly maintained machinery
  • Common Scenarios
    • Pivot pins on construction equipment with hardened grease
    • Tractor and farm implement fittings clogged by dried grease
    • Automotive suspension or driveshaft Zerks that have been neglected
    • Lawn equipment or industrial bearings locked by rust or old grease
  • How It Works
    • Loaded with penetrating oil (e.g., WD‑40 Specialist, PB Blaster, Kroil)
    • Hammer‑driven piston hydraulically forces solvent into the clogged passage
    • High‑pressure solvent softens or breaks up hardened grease
  • Key Benefits
    • Clears blockages in minutes without disassembly
    • Eliminates the need for heating joints or replacing bushings
    • Prevents costly repairs by restoring lubrication
  • Field Use
    • Fully manual tool—no power or air required
    • Compact and easy to carry in a toolbox
    • Ideal for remote or off‑grid job sites
  • Compatibility
    • Designed for standard grease Zerks only
    • Attaches via a grease coupler
    • Not suitable for sealed bearings without fittings
  • Summary
    • Used whenever a grease gun fails to force grease into a fitting
    • Cost‑effective solution across agriculture, construction, automotive, and industrial maintenance
