Macnaught KY-N SUPERGRIP Grease Coupler, 1/8" NPT - Set of 10

The Macnaught KY-N is the NPT version of the SUPERGRIP grease coupler. It does the same job as the standard KY, but it has a 1/8" NPT inlet for grease guns, hoses and pumps with an NPT thread. It snaps onto a grease nipple, grips with its jaws and twists and pulls off. Macnaught says it fits most grease nipples (manufacturer-stated).

NPT is the American pipe thread, used mainly on US-made 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. 1/8" NPT is not the same as 1/8" BSP, so check the thread on your gun first. Macnaught rates it 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 (manufacturer-stated).
