Rated 4 out of 5 by BruceB Good product
I used this item to replace the broken head on my Joeblow pump. Fitted with no problems and works fine. Good secure clamp action, does not leak when inflating. Have not tried it on Schrader type valves though.

Grips my Michelin prestas securely with no leaks. 120 pounds inflated on first attempt. Great product.
