Macnaught B2-SG Booster Gun with Safety Guard

The Macnaught B2-SG is a booster gun for air-powered grease pumps with a trigger hand guard fitted to protect the operator. It boosts the grease pressure at the nipple.

A booster gun is not a hand-filled grease gun. It has no barrel or cartridge. It connects by a hose to an air-powered grease pump and boosts the grease pressure at the nipple. When a nipple is seized and no grease flows, you pull the trigger several times and each squeeze boosts the pressure until grease flows. The inlet is 1/4" NPT(F), an American pipe thread (female). It suits grease up to NLGI 2. NLGI 2 is the common general-purpose grease grade. Choose the B2-SG if you want the hand guard on the trigger. Choose the plain B2-01 if you do not need the guard.
