4-Jaw Grease Gun Coupler 1/8 in BSP

A steel coupler that fits onto the end of a grease gun and grips a grease nipple with four jaws while grease is pumped in. The knurled collar gives a firm grip, and the female 1/8 inch BSP thread screws onto the gun's outlet. Four-jaw holding keeps the coupler on the nipple under pressure, which reduces spills and makes greasing machinery and vehicle joints cleaner. It measures 37 mm long and 15 mm across.
