Mintcraft FDQ910 Air Inflation Kit 4 Piece

• "MINTCRAFT" INFLATION KIT
• Air Inflation Kit Piece of 4
• Kit contains inflation adapter, tapered inflation nozzle, inflation needle, tire nozzle.

I purchased this set for the tapered inflation nozzle. It fits nicely into a pilates ball. The nozzle and the basketball needle are the same size. You should note that, when using this with a standard bicycle pump, you have to push down the lever on the pump to lock them into place. It looks as though these pieces screw in, but they do not on my pump. I have tried to measure these as accurately as possible and will list them in order that they appear in the picture.

Basketball needle: 1/4 inch

Tapered nozzle: 1/4 inch

Inflation adapter: 5/16 inch both ends

Tire nozzle: 5/16 inch
