The MotoMaster Premium Lever-Action Grease Gun is designed specifically for heavy-duty, daily use. This grease gun is built to take extreme punishment. The pump head is made from a heavier and reinforced cast-alloy material capable of withstanding pressures up to 17,500 psi (1200 bar). The gun develops 10,000 psi (690 bar) and can push through most blocked or restricted grease fittings. It features an additional grease intake valve, Short Stroke Valve, and is designed to allow the user to pump grease with minimal handle movement. The Short Stroke Valve is a valuable feature when the grease gun is being used in confined work spaces, commonly encountered on auto, truck, farm and construction equipment. It also features a very robust grease storage and delivery system. This grease gun has it all!
