Hi, I have a Problem with my Tire valve as it keeps leakingg air. I drilled a hole in the end cap, placed the tire valve through, and glue gunned the space around it to seal it. now everytime pump into it, It leaks out right away and doesn't pressurize.

please help me with my problem.

What did you use to glue it in with?

Is it a threaded schrader valve? If so then you should have threaded the end cap and used some pipe joint compound or some Teflon tape to seal it.

I put a little PVC cement around mine when I did it. The hole should also be a pretty tight fit to start with. I don't get the valves separate though, I go to the local bike shop and ask for old tubes and cut them from there, leaving the base, so this might not work as well.

Well on the label of the pack, it say: Tubeless Tirevalve. TR413 .53 rim hole. 1 1/4 long

And I used a hot Glue Gun to glue it in.

That may be the problem then. Hot glue is good for creating airtight seals but tends to get cracks in it or completely tear off when under high pressure. Use epoxy to secure the valve and Plumber's Goop to seal it.

I don't have any goop at the time being, Would pvc cement work?

[CD-R]

No, PVC cement works only on bonds between PVC only parts. PVC cement does what is known as "solvent welding". Essentially, it dissolves the two pieces plastic, and then let's the solution harden together.

Actually, CD-R, I've noticed that PVC cement worked for me doing the same thing, because all it is, is a strong adhesive. Maybe it only worked as a coincidence but i dunno...

I know this is kinda old, but use gorilla glue. Glue both internally and externally. It may take a could times but it will stick after a while. (Wont leak)

I used Barge Cement for mine. When I take off and put on the pump's end, It keeps getting looser and looser. I dunno If I should use epoxy putty, or goop... Any suggestions PM me.

Plumber's Goop works well on rubber, for me anyways.

And PVC cement shouldn't work, unless the tire valve is made out of PVC. All it really does is partially dissolve the PVC, then evaporate (as someone already said). It's not so much "cementing" as it is "welding".
