Ask JSR about that one. :wink:

I have used epoxy on copper launchers up to 300psi with no leaks or failures.

By far one of my favorites Ive seen- just a few questions though. What did you seal the fittings with? With epoxy or soder?
And how does it perfrom?

I love this little thing,although I am wondering about the Flow capability of the blow gun to pilot a gun like this,does it work well?I plan to use a blow gun similar to this should it work well?
