    Tyre valve connectors

    Hi all
    I have a question concerning Tyre valve connectors, which members may be able to help me with.
    During my many years of bike ownership I have always used my old trusty manual foot pump to adjust tyre pressure, my 2014 Trophy which I have owned from new being no exception. It also fits the car as well (Lever type connector)
    Recently, a neighbour kindly gave to me a plug in electric tyre inflate. I first used it on my car and it worked great, should have had one of these years ago I thought. So went off and bought the correct electrical plug in connector to suit the Trophy's power outlet so I could use the pump on the bike.
    However, when I screw on the small brass connector onto the bikes valve, it does not seal and air leaks out very quickly.
    My question is, are screw on type valve connectors not compatible for both bikes & cars? If not, can I purchase a type that is?
    Best regards
    Rob H

    My guess is that the brass valve on that pump is just a little too deep for some valve stems, the Trophy does seem to have a fairly short valve compared to other bikes/cars that I've owned.
    You could try and add another sealing washer on the inside of that brass valve, that may take up the space and make a seal?
    Or find another 12V pump that happens to have a not so deep seated valve.

    I have a relatively cheap Electric pump that I purchased from a Supermarket
    and the screw on connector works perfectly with no leaks.

    Is there a rubber washer inside the connector.Or you can file the end of the connector to shorten it a little bit

    To answer your question Robert H, yes it should screw on as they are universal fittings.

    As previously said checking or adding a rubber washer may be enough to make the seal.

    Another way is you can chop off your lever type valve (or but a spare one from any car accessory shop) and splice it into the tube.  If you buy a new lever type valve connector it will come with a jubilee clip and serrated conical insert into the tube.  Like this:

    If the Trophy's tires are the only tires you've tried the new compressor on, I would try it on the car, or something else, to see if the fault isn't with the compressor's attachment.  As has been stated, the valve stems are universal in size.  I have a cheap 12v compressor, and it works fine.

    Thank you members for your great advice.
    I found at work in the engineering work shops, a suitably sized "O" Ring which fit snugly inside the connector. This fixed the issue and the pump works fine on both the Trophy and the car.
    Interestingly, I have since found out the pump came from a Mercedes Benz car (Which are supplied as standard, apparently)
    So, perhaps something none standard about them. Anyway my problem solved, so did not have to discard it.
    Thanks again
