Valve Bicycle

does anyone know how to change the valve size on an inline dual head alloy mini bicycle pump? please?
Usually dual head pumps have to parts in the head.
A rubber 'grommet' and a hard plastic pin.
Usually, you flip both to get them to work.
The grommet has to sides, one side has a larger opening, the other much smaller.
The plastic piece usually has one side with a 'pin' and the other side sort of hollow.
For Schraeder (car valve type) have the large opening out, with the pin in the same direction.
Oo <<
For Presta (narrow road bike tires) you want the smaller opening out, and the pin, pointing in toward the pump.
oO>>
So to change, you just 'flip' both each time.
Good Luck

How to Repair a Bicycle Tire : How to Use a Presta Valve Adapter
Do the valve caps on bicycle wheels matter?
Mine mysteriously is missing and the air won't stay in the tire, but I don't know if the tire is damaged of if the cap matters. Can anyone help?
Yes and no.
The presence of caps prevents accidental pressing of the stems.
The lack of the caps has no functional use, except preventing the above problem.
If the air will not stay in your tire, you have a flat. You could have a damaged valve stem, or a hole in the tube. Either way, you'll have to buy a new tube. Most reputable shops will sell patch kits, but rarely (if ever) use them.
