NOVINO 4-Way Grease Zerk Tool | Remove, Install & Retap Fittings (1/4-28 SAE, M10x1, M8x1)

Introducing the NOVINO 4-Way Grease Zerk Tool — a compact, rugged maintenance companion designed to simplify grease fitting work on a wide range of equipment. Built with durable galvanized alloy steel and engineered for repetitive use, this tool streamlines tasks that once required multiple dedicated tools, helping you move from tough spots to smooth maintenance with less downtime. Its thoughtful design supports common grease zerk configurations, making it a versatile addition to any shop, farm, or job site.

Two socket sets form the core of the tool, covering different thread standards to minimize swapping. One set handles 1/8-NPT PTF grease zerk fittings and M10x1, with hex sizes 3/8" and 7/16" for a secure grip. The other set accommodates 1/4-28 SAE and M8x1 fittings, with hex sizes 5/16" and 3/8". The galvanized construction resists corrosion and maintains strength under demanding conditions, ensuring consistent performance across use after use.

Four-in-one versatility

• Remover and installer: silver sockets extract damaged or broken fittings and install straight or angle fittings at 30°, 45°, 65°, and 90°.
• Thread cleaner and restorer: black taps on the cross ends clean threads and support proper re-tapping when needed.
• Repair and maintenance: use the tool to re-tap holes and maintain healthy zerk threads for future servicing.
• Time-saving design: consolidates multiple grease fitting tasks into a single tool, reducing trips to the toolbox across various machines.

Practical use across equipment

From tractors and loaders to lawn mowers, excavators, and automotive work, this tool is built to meet diverse maintenance needs. The four-way approach helps with extraction, installation, threading, and repair in environments where space is tight or fittings are stubborn. Visual clarity, tactile feedback, and reliable grip come together to support efficient, repeatable results without overreliance on guesswork.
