    what are the little rubber tubes in some patch kits for?

    pyramid puts them in their kits, and i haven't got a straight answer.

    I always thought they were for blowing through onto the rubber solution when on the inner tube to dry it off more quickly before putting on the patch

    I always thought they were for smoothing the rubber cement, although I've never tried it...

    They were for the Dunlop type valves that I had on my first bikes in the 1940s. I think there are still plenty of bikes in the 3rd world with those valves.

    AndrewP is probably right - the early Dunlop valves were just a rubber tube inside the metal valve bit- same principle as a heart valve they let air in but collapsed to prevent air from coming out

    My curiosity led me to google "Dunlop valve", and this page came up:

    It details the history, construction, etc. of a dunlop valve and it shows the rubber tube thingy.

    http://www.flying-scot.co.uk/components/woods.html

    AndyP was right.

    Learn something new every day. I figured it was for spreading the rubber cement around too.

    I used it to smear the glue around when I patched a tube last night.

    In the third world? I don't think Japan is a third world country and I would say as a guess 95% of bikes here use them. Probably more.

    Relax. I'm well aware that Japanese bikes use them. He wasn't dissing Japan in the slightest. Dunlop / Woods valves aren't as common in North America or most of Europe as they are in Asia.

    My Joe Blow Pro floor pump, BTW, has and adapter for Dunlop valves. Never seen one, or even knew what they were, but now I know ("and knowing is half the battle" - GI Joe ).
