Woods Valves

How do these babies work? I've got hold of some Woods tubes for the Baines Eccolite, but I can't seem to inflate them. My best guess is I need to screw down the locknut to make then airtight but even using all my considerable strength ( :lol: ) I get an instant deflation as soon as I remove the pumphead.

    fit to wheel , locate tyre. reassemble valve inflate.

    all the "valve" is is a collapsable tube. that is compresed by the air in the tyre. if the tube is kinked it may be stopping it closeing. have a look at it.

    Woods valves come in two types. For both of them all you need do is remove the dust cap, fasten pump and pump.

    The dust cap has a screw thread, some older bike pumps have a rubber tube secreted in the handle that will screw onto the valve. Other 'push on' pumps need to be held firmly against the valve.

    Both valve types have the main valve body held in place by the central knurled nut ... undo it and the valve core comes out. One type has a rubber tube as the valve (replacement tubes are sometimes included in puncture repair kits) the other type has a more efined valve. You do not need to undo the knurled nut to add air... but if the valve has not been used in a while it can be a bit sticky at first but will suddenly let air in.

    Cheers, Phil
