I have one of those but it vanished a few weeks ago.I use a small air chuck like this on my air hoses to inflate motorcycle tires .....
I need to get one of those, because I found that they take a bend that suits my valve stems.I also have the long dual head style like this but it seldom fits a motorcycle wheel. It does work well on my car tires though .....
In one service station I was in the habit of bending the fitment, and the owner kept on straightening it for the next time I came in.
Eventually the thing busted and left a nasty cut on my hand.
