Wilmar Corporation W54224 Hd Grease Gun Coupler 4000 Psi

Product Description

The WILMAR CORPORATION W54224 is a heavy-duty grease gun coupler designed for use with most hand-operated grease guns. It connects the grease gun to standard grease fittings and delivers lubricant under high pressure, making it a reliable component for routine maintenance tasks in automotive, industrial, and equipment service environments. The coupler is rated for a maximum working pressure of 4,000 psi and a burst pressure of 8,000 psi, indicating a substantial safety margin under demanding operating conditions. The 1/8 inch NPT connection is a widely used standard thread size. Installation requires no special tools in most cases, and the coupler weighs 2.65 pounds.

This coupler is suited for use in garages, fleet maintenance shops, and field service applications where hand-operated grease guns are used to lubricate chassis fittings, bearings, and other grease-zerk-equipped components. Its high working pressure rating makes it appropriate for both light-duty and more demanding greasing tasks on trucks, trailers, agricultural equipment, and industrial machinery. The 1/8 inch NPT thread makes it compatible with standard grease gun hose ends and fittings commonly found in professional service settings.

Installation Notes

This coupler is typically installed by automotive technicians, fleet maintenance personnel, or equipment service professionals. Before connecting or disconnecting the coupler, relieve any pressure in the grease gun and wipe the fitting area clean to prevent contamination. Thread the coupler onto the grease gun hose end hand-tight before applying a wrench to avoid cross-threading the NPT connection. Follow equipment manufacturer guidelines and applicable workplace safety practices when working with pressurized lubrication equipment.
