Pro-lube G77RF-18/N Dual Pistol Lever Grease Gun 14 Oz

Product Description

The PRO-LUBE G77RF-18/N is a dual-action pistol and lever handle grease gun built for professional lubrication work in mechanical, HVAC, and industrial service environments. It delivers up to 7000 psi maximum operating pressure and holds a 14-ounce cartridge or up to 500 cc in bulk fill mode. The gun ships with a 6-inch rigid pipe extension and an 18-inch flexible hose coupler, giving technicians two reach options without switching tools. The powder-coated aluminum and steel construction keeps the unit durable under daily shop and field use. Output is rated at 26 strokes per ounce for consistent, measured delivery.

This grease gun suits residential and light commercial maintenance applications wherever chassis, bearing, or fitting lubrication is required. It is appropriate for HVAC equipment with grease-type motor bearings, plumbing and mechanical equipment with zerk fittings, and general preventive maintenance programs. The dual pistol-lever trigger mechanism accommodates either grip style depending on access and operator preference. The included rigid extension and flexible hose let technicians reach tight or angled fittings without repositioning the equipment being serviced.

Installation Notes

This grease gun is installed and operated by HVAC technicians, mechanics, and maintenance professionals working on equipment with grease-type lubrication fittings. Before servicing any motorized equipment, de-energize and lock out the unit per applicable safety procedures. Avoid over-greasing bearing cavities, as excess grease can damage seals and cause premature bearing failure. Verify the coupler is fully seated on the zerk fitting before applying pressure to prevent grease from bypassing the fitting.
