    This small tube is used to re-build a Woods valve. I have never seen the valve, but I heard about it.

    They are provided to assist you in 'rolling' out any small air bubbles (from center of patch to perimeter) without stressing the bond as the glue sets up.

    Primitive check valve.

    daniell is right, the bit of tubing goes on a so-called Woods valve. The valve stem of a Woods valve has a closed metal tube with a hole in its side. Sliding the rubber tubing over that tube closes the hole. At pumping, the air pressure expands the rubber tubing a bit and allows air into the tire. The little piece of rubber tubing would often rot and break, resulting in a sudden flat. Photo shows two valve stems.

    I've only seen two of those in my life, both on really cheap bikes from strange countries, and I failed to figure out how to air either of them up. Of course, that's why they were in the shop in the first place. They got nice, normal tubes and the customers went away happy.

    Woods Valve = WTF?

    I am speechless. Except for wondering if they delivered any embarrassing sounds as they were being pumped up.....

    No, never heard any, and have pumped on many of those. In Germany and Holland (where they're called "Dunlop" valve) all "transportation bikes" had these until they were replaced with a newer version using an actual check-valve inside.

    Since these stems were held in place by an easily-removed collar nut, it was easy to take the stem out, remove the rubber tubing and put the stem back in on a bicycle belonging to someone you couldn't stand. Kids did this to teachers, for example. Did I do this? Never.

    Wow, that takes me back. I remember those valves on a couple of bikes growing up.

    As I recall, these were found on the "English racers" my sisters had.

    Thanks for the memory trip.

    Cool that the patch kit included parts for such a repair. Never seen that in any patch kits before.

    Japan has 'em

    Most 'everyday' bikes in Japan come with this type of valve so they are pretty common here.

    The winner of the best foreign film oscar this year, a Danish film called In a Better World, had kids taking the valves off each other's bikes... It was set in current time...
