Finally found a kit with a proper inflation straw that actually fits snugly – no more air leaking while I pump. The two ball plugs are solid and the threading matched perfectly. Exactly what I needed to get my old ball working again.

The two ball plugs fit perfectly and the inflation straw made setup a breeze. It’s exactly what I needed to replace the worn-out parts on my ab wheel.
