Pro-lube GBP/6/HC/14/4/N Grease Gun Standard Coupler

Product Description

The PRO-LUBE GBP/6/HC/14/4/N is a standard grease gun coupler designed for use with grease guns in lubrication service applications. It features a 1/8 inch NPT thread connection, allowing it to mate securely with standard grease fittings across a range of equipment. The coupler provides a leak-resistant, pressure-rated connection that transfers grease from the gun to the fitting without excessive bleed-off. It is a compact, single-piece accessory installed by maintenance technicians, lube techs, and general service professionals working on mechanical equipment in industrial, commercial, and fleet maintenance environments.

This coupler is suited for routine lubrication tasks on machinery, motors, bearings, chassis fittings, and other equipment that accepts standard grease zerks. The 1/8 inch NPT thread makes it compatible with a wide range of manual and pneumatic grease guns. It is typically used in shop environments and in the field wherever scheduled greasing is part of a preventive maintenance program. The single-unit packaging makes it a convenient replacement or spare for a standard lube cart or grease gun kit.

Installation Notes

Installation is performed by maintenance technicians or lube service professionals. Before replacing a coupler, relieve any residual pressure in the grease gun and ensure the gun is not connected to a pressurized air supply. Thread the coupler onto the grease gun outlet hand-tight, then snug with an appropriate wrench - do not overtighten NPT fittings. Inspect the connection for leaks before returning the gun to service.
