Working on my first BB/Airsoft gun, i want to create it perfectly. Because most of the gun will be constructed from PVC, i come here to ask whether epoxy or PVC primer+glue would work the best. Which would would be best for bonding down PVC to PVC-I'm sure its primer+glue, but prove me wrong otherwise-, and for bonding PVC to other materials (metal)


Thoughts? Suggestions?

Primer+Glue. Thats why its called PVC glue

Well yes. As i've stated in my "description", but i still have doubts..ever since my last pneumatic exploded.

Roughening up the contact areas and using proper epoxy is just as effective, I use such construction techniques up to 400 psi without failure.

why did it blow? did it have DWV on it or what?

Unless there was a crack or it was a bad fitting, it shouldn't of blown if it was pressure rated, used below the rating and the primer and glue were used properly.

For bonding metal + PVC, try using threaded adapters.

But yeah, best stick with PVC glue and primer, make sure the glue is meant for pressure and check with the PVC too.


Also browse the forum for a link to the IPEX solvent welding course, you should try it, so you know what you are doing when it comes to PVC solvent welding. You'll get a free pen and certificate too.

if you do it right it will not fail. i actually had a piston valve "blow up" because i was smart enough to not put a bumper in and the pipe itself failed, but the solvent weld joints were still intact.

if you apply it properly, it will not fail, but that is true of epoxy too. i recommend pvc cement and primer.

Nope, it was 500 PSI rated PVC. The glue came loose on one of the joints while i was aiming.

There's your problem

Try <A HREF="http://www.spudfiles.com/forums/solvent ... l">this</a> it's worth it.

You probably didnt let it dry long for 24 hours but if you did just read through the solvet welding thing Crowly has a link too.
