What kind of epoxy would I want to use to glue a fill valve into place? I tried superglue and normal glue but it still leaks ( it was put on uneven) so what kind would be best?

I use PVC cement, it works great and is reliable

Edit*
what type of fill valve do you use? a schrader?

It is a metal tractor tire valve, its just a schrader with a monkey grip rubber clamp on it.

is it threaded. if so try locktight. my first cannon had a cut out piece of inner tube with the valve attached with was held a sealed by putting a washer underneath and pressing it against the barrel.

mkay, so the base of the valve is rubber right? if so, then PVC cement should do the job, if not, well I dunno what to say, I have only used PVC cement

Maybe some other type of glue like wood glue or regular epoxy

geez you guys around here make me wonder sometime, woodglue is not epoxy, superglue is not epoxy, pvc cement IS NOT EPOXY, JB Weld is epoxw, loctite epoxy is epoxy, PC11 is epoxy. Pull you heads out and realize that sometime you can just dig through your junk drawer and find something that might work and go down to your local hardware store and get some stuff that will work.

i agree big grib. Just use EPOXY the regular good ole EPOXY. Just lop on a Big ole glop and your done.

Some people seem confused as to what epoxy is, and even more seem to think that PVC glue can be used for normal gluing operations.

PVC glue is for joining together tightly fitting PVC pipe and fittings, with the aid of primer. That is ALL it is for. Gluing together random parts that were never meant to be glued together is the job of epoxy.

Also, if you can't get a threaded shrader, just use a quick connect and tap it into the chamber. And if anyone says they don't have a compressor so they can't use quick connects... :violent1:

Well I guess PVC cement could melt the plastic around the threads so they tightly lock on...

Personally I'd just go with Teflon Tape and some JB Weld for extra security.

i don't have a compressor...jk
yeah, get real epoxy, it's like 6 bucks for a two sided syringe thing and every hardware store has it
i really don't have a compressor, i should go get one, too bad i'm broke

That remark was referring to how many people seem to think you can't attach a quick connect to anything but a compressor. People too dumb to put a threaded hose barb on a bike pump and attach a quick connect really shouldn't be working on these things.

I assumed the shrader was unthreaded, because if it was threaded, he could just tap a hole in the pipe and attach it like that.

I don't have a compressor either, but my 95 cubic foot nitrogen tank with 0-500 psi reg has sufficed for now.

Quite... *points with pipe... 22mm OD copper of course, honestly, do you think I smoke?*

I use a cheap-ish QD fitting type for my launchers, initially fitted to my homemade pump. Cheap as in (relatively) low flow, but it's rated all the way up to 35 bar (~500 psi). However, I don't get much flow from the high pressure track pump, and it will still cope with ~20 SCFM, which is more than I need for any project I can see in the future, and more than I will get from any compressor I might ever buy in the near-ish future.
