Just a quick question

From your experience, how much pressure can Plumbers-Goop ("Amazing Goop") hold? I used it to seal a tank on my pneumatic, and I don't want to put too much pressure in it.

Thats a good question, since you have some figure out a safe way to test it and inlighten the rest of us.....

Yeah, then we'll all know.

How big is the hole you're trying to seal? Your question is like asking how much pressure steel can hold...

I used it a couple times to seal a threaded brass fitting in an unthreaded hole (it probably got partially threaded just from putting it in there but). It holds at least 100 psi. Also used it to seal modded sprinkler valves where the solenoid goes. Seems fine but I'll epoxy more. If your talking about sealing on an end cap or something than that's beyond me.
I'm a big fan of putting myself and a pump on one side of a door and the potentially explosive test subject on the other side then shaking it around.

Alright, here's the deal. I haven't yet gotten a chance to test out how much pressure it can hold, but I'll try to soon.
The set up is like this- A fire extinguisher tank, with a 1/2 brass ball valve glued inside of the top. There is also set screw (that I made out of a 5/16" bolt) that is wrapped in teflon tape holding the two pieces together. Before I shoved the ball valve into the extinguisher, I wrapped the bottom of it with lots of teflon tape. then, I coated the inside of the neck of the extinguisher in goop. after I shoved the ball valve in, I put the set screw in, and coated all of the connection with goop.

I actually happen to know this from experience.
Plumbers Goop will start to fail at around ~50 PSI of constant pressure. It begins to bubble, and will then rupture.
They've changed the formula of it- it used to be unstoppable, now it's pretty suck. Best to just roll with JB Weld.

Alright, I'll try putting about 75 psi into it, and if it begins to fail, I just might have to peel it all off, and re glue it with something stronger.
