MACNAUGHT AutoSwitch™ 450g Pistol Grip Grease Gun

Experience unparalleled efficiency and reliability with our state-of-the-art grease gun, designed to meet the rigorous demands of industrial applications. An industry first, the AutoSwitch™ Grease Gun allows you to seamlessly switch from high flow to high pressure automatically. Skilfully engineered with dual pistons, this grease gun can build pressures up to 12,000 psi (82,700 kPa / 827 bar) by hand.
