So I got my first wing with a boston valve after using Duotone where the pump nozzle locks on to the valve. The nozzle I'm using is one where you push it into the valve, but every time you pump, it pops back out. Am I missing something?

The nozzle I use:


The valve:

I asked this same question when I first tried the Boston valve. Sounds like there are different tolerances on the valves and some work and others don't. People say you need to push it in and twist to make it stick and sometimes you need to put some tape around the valve to make it bigger. Honestly, it never worked for me and I found that the valve style basically sucks with conventional adapters.


the good news is that there is a solution. Just avoid the frustration and buy this. Works perfectly.

As a long time user of duotone wings the advice I'm giving you MAY be applicable. Apologies if it isn't. When pumping up a wing I rotate the nozzle a full turn anticlockwise. This puts tension on the tubing so when the nozzle engages with the valve it automatically locks in and stays in the locked in position. If I don't do that, what I find often happens is the valve will wiggle around while the pump is operating and the nozzle rotates clockwise out of the valve and falls out. Hope this helps

I did the same thing with my duotone. But with the boston valve there is no lock at all. It only stays in place by friction.

Velocircaptor is dead on. Buy it now.
