NOVINO 4-Way Grease Zerk Tool — Compact Alloy Steel Grease Fitting Remover & Thread Restorer (Galvanized)

If you service machinery or vehicles with grease fittings, this cross-style tool consolidates four essential functions into one hand-held unit so you can remove broken fittings, install new ones at multiple angles, clear clogged threads, and re-tap damaged ports without carrying a larger tap set. Two socket ends handle the common SAE and metric zerk sizes while the opposite cross arms provide threaded cleaning taps. The galvanized finish resists rust in workshop and outdoor environments.

How does this tool remove and install damaged grease fittings?

The NOVINO cross has two silver socket ends designed specifically to grip and turn stubborn or rounded zerk fittings. They fit common sizes so you can extract broken fittings or seat replacements cleanly, including straight and angled fittings up to 90 degrees.

• Silver sockets sized for 3/8" (9.5mm), 7/16" (11mm), 5/16" (7.85mm) and 3/8" (9.5mm)
• Works with straight and 30°, 45°, 65°, 90° angled grease fittings
• Galvanized alloy steel construction for torque without deformation
• Compact cross design for easy leverage in tight spaces

Can it clean and restore stripped or clogged grease fitting threads?

Yes — the cross arms include black threaded taps that act as thread cleaners and restorers to re-cut and clean grease ports. They remove hardened grease, debris, and minor thread damage so replacement fittings seal and pump grease correctly.

• Black taps sized to restore 1/8"-NPT, 1/4"-28 SAE, M8x1 and M10x1 threads
• Clears hardened grease and metal filings from ports
• Restores thread engagement to help new fittings seat properly
• Useful as a preparatory step before installing replacement zerks

Which machines and jobs is this tool suited for?

The NOVINO grease zerk tool covers a wide range of agricultural, automotive, and industrial needs — from lawn tractors to heavy construction equipment. Its size and functionality make it a practical addition to service carts, farm toolboxes, and mobile mechanics' kits.

• Designed for tractors, loaders, excavators, mowers, and rotary cutters
• Works on automotive and truck grease points and marine fittings
• Good for shop use, field repairs, and preventive maintenance rounds
• Durable enough for frequent, high-torque tasks

What sizes and thread standards does the NOVINO 4-way handle?

The tool matches the common SAE and metric zerk fittings used across equipment brands. It includes sockets and taps that cover both 1/8" and 1/4" SAE threads as well as M8x1 and M10x1 metric fittings so you won’t need multiple single-purpose wrenches.

• Fits 1/8"-NPT PTF and 1/4"-28 SAE thread forms
• Compatible with metric M8x1 and M10x1 grease fittings
• Socket hex sizes: 3/8" (9.5mm), 7/16" (11mm), 5/16" (7.85mm)
• Cross-arm taps for cleaning and re-tapping standard zerk ports

Who is this for: The NOVINO 4-Way Grease Zerk Tool is aimed at mechanics, farmers, landscapers, fleet technicians, and DIYers who perform regular lubrication maintenance. If you need a single, rugged tool to extract broken fittings, install new ones at awkward angles, and restore or clean threads on-site, this compact cross tool simplifies those tasks and reduces the number of separate hand tools required.
