Wilmar Corporation W54228 Lock on Grease Coupler

Product Description

The WILMAR CORPORATION W54228 is a lock-on grease coupler designed for use with standard grease guns in automotive, industrial, and fleet maintenance applications. The coupler attaches to a grease fitting with a single, minimal push and releases with the same low effort, allowing the technician to keep both hands free to operate the grease gun once the coupler is locked in place. The positive seal holds up to 10,000 psi during grease delivery, preventing leakage at the fitting connection. The compact body profile fits into tighter spaces than conventional lock-on couplers, making it practical for hard-to-reach fittings on chassis, suspension, and equipment joints.

This coupler is suited for professional shop environments and field service work where grease fittings are accessed frequently and efficiency matters. Sold in a package of 10 units, it is a practical stock item for service bays, fleet shops, and maintenance facilities. The low-effort locking mechanism reduces hand fatigue during high-volume lubrication service on vehicles, agricultural equipment, and heavy machinery. It is compatible with most standard grease gun accessories and fittings commonly found in trade and industrial settings.

Installation Notes

Installation is performed by lubrication technicians and general service mechanics. Before connecting, verify the grease fitting is clean and free of debris to ensure a proper seal. Push the coupler squarely onto the fitting until it locks, then confirm seating before applying pressure. When removing, release the coupler per the mechanism design rather than pulling forcefully to avoid fitting or coupler damage.
