NOVINO Grease Zerk Tool 4-Way Multi-Tool Kit — 2-Piece Cross Set for 1/8" NPT, 1/4"-28 & Metric Threads, Thread-Repair & Extractor

If you work on agricultural, construction or automotive equipment, damaged or clogged grease zerks slow maintenance and risk poor lubrication. This two-piece NOVINO kit combines threaded taps and removal/install sockets in a cross-style tool to tackle the most common zerk sizes: 1/8" NPT/PTF, 1/4"-28 SAE, M10x1 and M8x1, plus common hex sizes (3/8", 7/16", 5/16"). It’s built from galvanized alloy steel to resist corrosion and stand up to routine garage use.

How does this tool remove broken or seized grease zerks?

The silver socket ends act as both extractors and installers: they slip over protruding or damaged zerk fittings to unscrew seized threads or press-fit new zerks in place. Because the tool accepts straight and angled zerks, you can work odd orientations without extra adapters.

• Removes damaged, broken or rounded hex grease zerks
• Provides leverage for stuck fittings in tight spaces
• Fits common hex sizes: 3/8" (9.5mm), 7/16" (11mm), 5/16" (7.85mm)
• Works with straight and angle fittings (30°, 45°, 65°, 90°)

Can it clean and restore threads so new fittings seat correctly?

Yes. The black tap ends are designed to re-cut and clean grease fitting threads, removing clogged debris and repairing damaged threads to accept a replacement zerk. Re-threading on-site saves time versus chasing out threads at a machine shop.

• Restores 1/8" and 1/4"-28 tap threads
• Cleans out hardened grease and dirt from the bore
• Helps ensure new fittings seat straight and seal properly

What sizes and fittings will this NOVINO kit cover?

The two-piece set covers both SAE and metric thread standards commonly used on farm and industrial equipment. Each cross-type tool offers two socket sizes and two tap/thread-cleaning ends, making the kit versatile for mixed fleets or varied machinery.

• Fits 1/8"-NPT/PTF, M10x1 threads and hex 3/8" & 7/16"
• Fits 1/4"-28 SAE, M8x1 threads and hex 5/16" & 3/8"
• Two cross-tools included for broader compatibility

How will this tool change routine maintenance tasks?

By combining cleaning, thread restoration, removal and installation into compact cross-tools, the kit reduces trip time, tool changes and the need for specialty parts when servicing greased points. It’s designed for quick field repairs so lubrication schedules stay on track.

• Makes on-site repairs faster and less fiddly
• Reduces downtime by avoiding shop visits for simple fixes
• Compact enough to keep in a toolbox, service truck or tractor cab

Who is this for: The NOVINO Grease Zerk Tool is made for mechanics, farmers, landscapers and maintenance technicians who service heavy equipment, mowers, trailers and trucks. If you need a durable, portable solution to extract broken zerks, clean clogged fittings and install replacements in both metric and SAE sizes, this two-piece alloy-steel kit provides a practical, multi-purpose option to speed up routine lubrication work.
