Wilmar Corporation W54202 Pro Grease Gun 4500 Psi

Product Description

The WILMAR CORPORATION W54202 is a heavy-duty lever-action grease gun built for professional use in automotive, fleet, and industrial maintenance applications. It operates on a short-stroke lever mechanism, reducing hand fatigue and improving maneuverability in tight or confined spaces. The chrome-plated finish over a knurled thick-wall barrel provides corrosion resistance and a secure grip during extended use. Maximum working pressure is 4,500 psi, with a burst pressure rating of 12,000 psi. Each pump stroke delivers 0.106 cubic inches of grease. A vented zinc die-cast head cap and air bleeder valve prevent air lock, while the positive lock mechanism simplifies cartridge loading. Both a pipe and hose fitting are included.

This grease gun is suited for service bays, fleet maintenance shops, and general industrial lubrication work. The short-stroke lever action is especially useful when working around chassis components, suspension joints, U-joints, and other grease fittings in restricted areas. It accepts standard 14-ounce grease cartridges, which are widely available across trade and supply channels. The comfort grip lever handle reduces operator fatigue during high-volume lubrication tasks.

Installation Notes

Loading and operation should be performed by a qualified technician familiar with lubrication equipment. Before attaching to a grease fitting, purge air from the barrel using the air bleeder valve to ensure consistent grease delivery. Relieve pressure from the gun before changing cartridges or fittings. Follow equipment manufacturer specifications for grease type and lubrication intervals.
