Removing broken brass fitting

[930dreamer]

Hello, I'm trying to remove a broken brass fitting in an air conpressor tank. I sprayed penetrating oil on it two weeks ago and let it sit. It's about 3/8 in diameter, I'm worried I'll break the easy out . Won't budge, don't have a heating torch only butane for solder. 930

go out and buy a cheap propane torch

Sorry I meant propane. Got one, I'll try that thanks.

if an extractor won't budge it you may be ahead to drill and tap before you break an extractor in it.

I've had good luck with using a hacksaw blade through the centre of the fitting to cut it into a couple pieces and remove it.Some minor cuts in the threaded bung of the tank will seal with the pipe thread dope on the new fitting.

If I drill the brass and tap, I'll need to tap with pipe tap correct?

I'm with krusty. just drill and tap it youll be done in 15 minutes
break off the easyout your in for some fun.

Pick up some left-hand drills - it's possible that when you get close to the diameter of the brass insert that the left-hand rotation might just back it out.

That's what I'm using and it's not budging. Tomorrow I'll try the propane torch.

yes, it will be pipe thread

You might have better luck with a pipe extractor than a regular easy out.I say might because in some situations ( brass) actually distorts when using any extractor and ends up tighter than it was.Probably better off drilling it.I've drilled a ton of em out like the other guys are saying.Hacksawed em and used a dremel or die grinder also.Goodluck!

Worse case scenario you could always cut that bung out of the tank and weld in a new one.

you can also pick up mapp gas for your propane torch, gets much hotter. Other than that I would just drill it

I have had better luck w/the square easy outs. The last brass fitting I needed to remove came out easy with a small propane torch and a square easy out.

Thanks everyone, I removed the piece with a square sided extractor, it was tight.
