Alemite 6616-G Grease Gun Hose Coupler Assembly

Product Description

The ALEMITE 6616-G is a grease gun hose coupler assembly designed for hand-operated grease guns used in lubrication maintenance work. The assembly measures 5.5 inches in length and includes an integrated check valve and swivel, which together prevent backflow and allow the technician to maneuver the coupler without twisting the hose. It is compatible with standard button-head fittings, making it a practical replacement or spare for general lubrication rigs in shop, fleet, or field service environments. Maintenance technicians and mechanics routinely use this type of assembly to restore full functionality to a grease gun setup quickly.

This coupler assembly is suited for hand-operated grease gun applications across a range of service settings, including automotive, industrial, and equipment maintenance. The standard button-head coupler compatibility means it fits the most common zerk-style grease fittings found on chassis, bearings, U-joints, and similar lubrication points. It is a direct-use component that does not require special tools to attach and is typically stocked as a consumable or backup part by shops handling regular lubrication schedules.

Installation Notes

Installation is performed by maintenance technicians and mechanics as part of routine grease gun service or repair. Before replacing the coupler assembly, relieve any residual pressure in the grease gun per standard practice. Thread or snap the coupler onto the hose end according to the connection type and confirm the check valve seats properly before applying grease. Inspect the swivel joint for free movement after installation to ensure no binding that could cause premature wear.
