So my schrader valve on my pneumatic is leaking. It only happens when I use my air compressor and its the only pump I have . ANy idea's on fixing the problem?

UPDATE:

Well I fixed the problem with the schrader. Just needed tightening (thanks for those who said that) but now it has shown me that at 2 bar my cha,ber has several leaks Cant wait for this epoxy to dry.

Tighten the pin inside?

Maybe its the fitting that makes it come loose?

More detail as to where it leaks out of?

btw is it a rubber one or metal?

get a special screw driver and take out the internals and make sure its clean
and still ok, but like thursto said, wheres it leaking from

if it's leaking from the valve core, you'll need to go down to schucks or something and get replacement valve stems and it comes with a valve stem remover. usually those seals dont leak but once the seal starts to go it is only a matter of time til it wont hold pressure at all. the kits usually come with 5 or 6 replacement valve stems and cost about 5 to 10 bucks depending on the quality of the valve stem remover. if it's leaking anywhere else you might just end up having to replace the whole assembly. but at least you know where to start.

every now and again one of my pnuematics had this problem, if its the same thing (leaking out of the top, at the base of the pin), all i would do was poke something flat and small down the side of the pin and gently tighten the small metal bar that holds the pin.
Or as ajdevi92 said, you can buy a special tool from bike/tyre shops that will do the job easier.

u can use epoxy and a hose clamp to hold shraders tight against pvc if its leaking around the shrader, also neoprene and superglue can create a good seal on pvc or the rubber of the shrader to stop small leaks.

More than likely, you have bent the pin in the valve core.

This happens, and is best fixed by replacement.

Take it out and replace it

Remove the stem, by unscrewing it with a valve stem removal tool, and check if it has any grit or dust on the seal or in the body. Blow it out with air and wipe the seal off. Reinstall and see if it fixes the leak. It doesn't take much to crap in the valve to keep it from sealing properly.

If you don't have a valve stem removal tool then go on down to the local hardware store and get a new valve, and pick up the removal tool while your there. It'll come in handy someday.

I think its just the stem needingtightening. It wouldn't be leaking from the sides as I put around 100ml of epoxy on the inside and around where I placed the schrader. Thanx for the advice guys. If it doesnt work I'll check the compressor's nozzle.
