Macnaught B3 Control Gun (Non-Boosting) B3

The Macnaught B3 is a control gun that does not boost pressure. It is the non-booster gun without swivel. It is the non-boosting counterpart of the B2 booster gun, for when you do not need the extra boost. The inlet is 1/4" NPT(F), an American pipe thread (female).
A booster gun (B2) connects to an air-powered grease pump and boosts the pressure at the nipple. The B3 does not boost. Choose the B3 if you do not need the boost. Choose the B2 if you want to clear seized nipples.
