Presta valve adaptor problems
So I have gotten about 3 different presta to schrader valve adaptors and I can't get any of them to work with a pump. I've tried a bunch of different pumps (gas station / floor pumps etc) and nothing seems to work. The problem is that I can't get the pump end to fully press in the little tip on the valve to allow air into the tube. It's either the pump or the valve adaptor being too short and not reaching. I guess it's just trial and error until I find a fit. Anybody else have this problem or have suggestions, tips?
Thanks!
Thanks!

Yes, three different lengths of the thread basically.
Thanks for the Sheldon link. I've recently got a newer bike using presta and before on my older bike it was always the 27 x 1/4" tires with the schrader valves. So I guess the trick is to unscrew the little cap there (like in the picture on sheldon's site) THEN put on the adaptor and pump. Figures that I wasn't having any luck with pumping into a closed off valve. How embarrassing... thanks all!
