is epoxy safe to use one a cannon

Unread postAuthor: donimic1313@hotmail » Tue Oct 23, 2007 8:50 pm

is epoxy safe to use on a cannon that will likely be pressureised to 20-100 PSI, and if not, what is a safe way to seal a cannon besides welding

What material are you using?

PVC can be solvent welded. copper is either soddered or compression fittings. Steel at hardware stores are normally threaded so you can use teflon tape for that.

epoxy is generally used for sealing leaks but jackssmirkingrevenge uses it in a multitude of ways.

next time try searching.

Epoxy should never be used to join pieces together, only to fill gaps.
(air leaks, solenoid hole, ect..)

There are copper guns on this site that are made with sanded fittings and epoxie. they have help upwards of 200 psi. so sand your pipe and fittings and mix your epoxie well and you'' be fine.

I'm pretty sure somone on spudfiles has a dad that uses epoxy to seal his big CO2 system which runs at about 800PSI. In other words, you should be fine.

epoxy is safe to use on cannons, if you mix it right and use the proper epoxy.

Jack on the fourms has used it up to about 300 psi, if i rememeber correctly, but that doesnt mean that you should take it to 300 psi.

What do you plan on using the epoxy on? If it is plastic, solvent weld. Never join plastic parts with epoxy. Don't listen to these post whore new people.

i disagree. ive used epoxy on pvc and it works very well. it may not "weld" the plastic like a proper solvent weld, but its strong enough that at 130 psi it will hold up very well.

again, it depends on the epoxy and how well you mix it. if you were to join pvc together i would also say that it would be better to solvent weld it, but i think that epoxy would work just fine.

Old doesn't neccisarily mean wise... and new doesn't neccisarily mean newb. :wink:

I plan to use epoxy to seal one end of a bolt for a semi-auto paintball gun, and from what I have seen 1/2" in in a 1/2"-2" pipe should withstand 100psi easily if made properly.

Ive seen epoxy that claims it's rated to seal up to 3500psi but that doesn't mean it will JOIN components safely. I don't want to attempt it on PVC, but I would consider it on copper for example. In which case I would just soder it.
For $5, I say just get the PVC cement. Just my .02 cents.

Don't act arrogant unless you have a valid point to support your actions. In this case, you are dead wrong. Properly prepared surfaces (PVC, ABS, copper, brass, steel, etc) bonded with properly mixed epoxy will hold A LOT of pressure. With Plastics, it is likely that the pipe itself will fail before the epoxy does. With metals, you can expect the joints to hold more than 400psi.

If you are attatching steel to steel, at least bolt it together and add an O-ring if you can, then seal any gaps with the epoxy. The rest has been said.

I have only used plumbers epoxy and from what i have read, there are many different epoxies out there. So it also depends on what kind you are using. It would be helpful if you respond to these rejoinders with comments. This is to help you :) so make use of it :D
