Oh boy! My first post!

I have a valve from an auto parts store, and it looks like a schraeder (God I hope I spelled that right :D ) valve, in terms of the threads, but the part that goes in the reservoir is covered in a tough rubber, kind of like an inner tube, but thicker. It has a ring of rubber at the top, so it won't pop out easily, then it tapers down until the rubber is gone, and the threads are exposed. I can't recall the brand name, and I'm not good with computers, so I can't do images. What I need to know is, if I lock the valve in place with super glue, is it safe to pressurize? I have already tried it at 80 psi, but I don't want to tempt fate by going higher until I know it's safe. Sorry for being vague, but any help is welcome! :lol: :lol:

Curse the auto store for being the only one within an hour's drive, and carrying one type of valve! :evil:

EDIT: Oh snap! I get spud bucks for posting! (Whatever those are, lol :lol: )

Yes sir, you are safe for pressurization. Though the threaded types of schraders (those with threads on the bottom end for screwing into the air chamber) are generally deemed safer and easier to use, I assure you that the type you have is perfectly safe for use. (I have used one up to about 125 PSI, with no problems).

Spud on!

just for clarification, the valve is mounted in the chamber and not just glued on top correct?

Is it one of these?

If so, drill a hole about the diameter of the neck (smaller is better) so it's really hard to push it through. Stop when it gets to the fat part. Use something like blue tac (aka tikky-tac, poster putty; it's that blue sticky stuff that's used in schools) to make a good seal. Mine doesn't leak at all.

Yes, glued on top would leak like crazy and do nothing.

Here's a picture of how I mounted mine. Black is the pvc, orange is the schrader, and blue is the blue tac.

It's schrader. I used to make that mistake all the time.

a message would be nice
like why you are showing us a quick disconnect
it has nothing to do with a schrader valve

Is that not a schrader, popoff, gauge and quick disconnect in one?

And you should have edited your post - otherwise someone will jump on your back about raising your post count.

He only added his extra message for the people who didn't actually look at the picture and notice it has a schrader, a pop off, a pressure gauge, and a quick disconnect.

P.S. No one cares about post count. :wink:

look in compressor parts-- that item is for an air tank that would be carried to a flat and such.
I did a how to/post about that valve months ago.
Post count? who cares, I dont

@ Flying_Salt

That's not it exactly, but it's essentially the same idea, i.e. hard to push through. The endcap to the chamber has a drilled hole, and I put superglue on the side of the hole. The valve is a bit more conical than yours, so it fits the side of the hole very nicely, and should not pop out, unless the pressure is obscene. Thanks to all who helped!
