Alemite 6704-A Grease Gun Hose Coupler Assembly 4800 Psi

Product Description

The ALEMITE 6704-A is a grease gun hose coupler assembly designed for high-pressure lubrication service in professional maintenance and fleet applications. Rated to a maximum operating pressure of 4,800 psi, the assembly measures 12 inches in length and connects via a 1/8 NPTF thread for a leak-resistant, tapered-thread seal. A built-in swivel fitting reduces hose twist and kinking during use, keeping the line manageable when working in tight or awkward service positions. This assembly is a direct-use component intended for installation and field use by lubrication technicians, fleet mechanics, and industrial maintenance professionals.

The 6704-A is suited for hand-operated grease guns used in automotive, agricultural, and general industrial maintenance settings. It mates with button-head grease fittings, which are among the most common grease fitting types found on bearings, chassis components, and power transmission equipment. The 12-inch hose length provides enough reach to access recessed or partially obstructed grease points without requiring the full gun body to be maneuvered into confined spaces.

Compatibility

Designed for use with hand-operated grease guns and button-head grease fittings. Connects via 1/8 NPTF thread.

Installation Notes

Installation and replacement are typically performed by lubrication technicians or mechanical maintenance professionals. Before replacing or attaching the coupler assembly, relieve any residual pressure in the grease gun and wipe the fitting and coupler clean of old grease and debris. Thread connections should be made hand-tight first, then snugged with an appropriate wrench — do not overtighten NPTF fittings, as the tapered thread is the seal. Inspect the swivel and coupler body for wear or damage before returning the gun to service.
