Macnaught KY SUPERGRIP 1/8" BSP Grease Coupler -Set of 10

The Macnaught KY SUPERGRIP is the standard coupler supplied with Macnaught grease guns. It snaps onto a grease nipple, grips with its jaws and twists and pulls off when the job is done. Macnaught designs it to fit most grease nipples and says it suits any greasing system (manufacturer-stated).

BSP is the British pipe thread used on most Australian and NZ equipment. The inlet is female, which means the thread is inside the coupler and it screws onto the end of your grease gun or hose. Macnaught rates this coupler for pressures up to 12,000psi. How to pick the right KY: choose the KY with a 1/8" BSP inlet for a 1/8" BSP gun, the KY-N for a 1/8" NPT gun, or the KY-M for an M10X1 gun. If you want a coupler that releases with one hand and has a built-in pressure relief, look at the KY+ safety coupler (manufacturer-stated).
