NOVINO 4-Way Grease Zerk Tool – Remove, Install, Re-Tap, Clean Fittings (1/8"-NPT, 1/4"-28 SAE, M10x1, M8x1)

Overview

The NOVINO Grease Zerk Tool is a compact, heavy‑duty 4‑in‑1 kit designed to help you install, remove, re‑tap, and maintain grease zerks and fittings. Built to withstand demanding maintenance tasks, this tool aims to streamline service when a zerk is missing or damaged, letting you keep equipment like tractors and mowers running smoothly.

Crafted from galvanized alloy steel, the kit is built to endure the rigors of fieldwork and workshop use. The design emphasizes precision and control, so you can handle tight spaces and awkward angles with confidence.

Two precision sets for broad compatibility

The kit includes two complementary sets designed for common grease zerk standards. One set fits 1/8"-NPT PTF grease zerks, M10x1, and fittings with hex sizes 3/8" (9.5 mm) and 7/16" (11 mm). The other set handles 1/4"-28 SAE, M8x1, and fittings with hex sizes 5/16" (7.85 mm) and 3/8" (9.5 mm). This pairing covers a wide range of applications, reducing the need to switch between multiple tools during a job.

What you can do with the 4-in-1 design

• Install new grease zerks with proper alignment and controlled engagement, supporting reliable lubrication for moving parts.
• Remove damaged or broken threaded zerks without harming surrounding threads or surfaces.
• Re-tap holes to repair 1/8"-28 and 1/4"-28 tap threads, enabling reuse of standard fittings.
• Maintain and keep fittings clean with the built-in thread cleaner and restorer, helping restore correct thread geometry.

Thread cleaner and restorer

The cross-end black taps act as thread cleaning tools, designed to clear debris and rethread grooves so you can reinsert the correct zerk fitting with greater confidence.

Remover and installer capabilities

The silver sockets function as both removal and installation tools for straight and angle grease zerks, including common configurations at 30, 45, 65, and 90 degrees. This versatility helps you reach fittings in recessed or awkward positions.

Durable, wide-ranging use

Designed to meet the needs of tractors, loaders, lawn mowers, excavators, rotary mowers, and rotary cutters, this kit covers many agricultural, industrial, marine, truck, construction, and automotive scenarios. The galvanized finish resists wear in tough environments and provides a reliable grip in oily or dusty conditions.
