Wilmar Corporation W54231 Grease Fitting Tool 1/4-28 Npt

Product Description

The WILMAR CORPORATION W54231 is an all-in-one grease fitting tool designed to install, remove, tap, and chase threads in 1/4-28 NPT fitting holes. It handles straight and angled fittings in 1/4 inch, 5/16 inch, and 3/8 inch sizes. A built-in broken fitting spiral removal tool addresses damaged or seized fittings without requiring a separate extractor. The slotted driver interface supports installation of 30, 45, 65, and 90 degree grease fittings, covering most standard Zerk fitting angles found in automotive, agricultural, and industrial lubrication applications. This single tool replaces several individual tools commonly kept on a grease service cart.

This tool is suited for automotive technicians, heavy equipment mechanics, fleet maintenance crews, and industrial maintenance personnel who routinely service grease points on chassis components, suspension joints, universal joints, and bearing housings. It consolidates tapping, thread chasing, fitting installation, fitting removal, and broken fitting extraction into one compact tool, reducing time spent locating the correct instrument during service work.

Installation Notes

This tool is intended for use by qualified mechanics and maintenance technicians familiar with lubrication system service procedures.

When extracting a broken fitting, ensure the surrounding threads are not damaged before reinstalling a new fitting. Follow equipment manufacturer torque and lubrication specifications for the components being serviced.
