Macnaught PG450 POWERGUN Li-Ion Grease Gun

The Macnaught PG450 POWERGUN is a cordless 18V Li-Ion battery grease gun, so there is no air line to run and no hand pumping. It takes 450g cartridges or can be bulk filled. The kit comes with two 3.0Ah batteries, a fast charger, a 1m flexible hose with a KY coupler, a shoulder strap and a carry case (manufacturer-stated).

Maximum pressure is 8500 psi (586 bar). It handles grease up to NLGI 2. NLGI 2 is the common general-purpose grease grade. A switchable valve gives you high volume for normal greasing and high pressure when a nipple needs more push. There is an LED light for dark grease points, a spring-loaded bleeder and motor overload protection. Choose the PG450 for high-volume greasing where you do not want to pump by hand. A hand gun such as the K29 FLEXIGUN is lighter and needs no charging (manufacturer-stated).
