Removing Angle Fitting on HF Pressure Pot

[randyrls]

Is it possible to remove the angled pressure fitting on the paint feeder tube of the HF pressure pot? It looks like that is some kind of "goop" on the threads.

I've read thru many of the message threads, and looked at the articles in the library on plumbing the pressure pot, but I can't get that stupid angle fitting off the pot. I've tried a 12" crescent wrench with a 3 foot extension pipe, but no dice! It is one with the paint tube attached. I'd prefer to remove it and put a short pipe piece in there as the angle fitting doesn't allow me enough clearance to attach a pressure relief valve on there. Threading on the pressure valve hits the top of the pot.

Propane torch? Heat gun?

Any suggestions appreciated.

I heated mine with a propane torch and it came out easily.

Get a real mans wrench!!!:biggrin:

Seriously, I used a 18 inch crescent and once it finally broke loose it was a piece of cake to unthread.

I could never get mine out. Cut off the pipe inside and just plugged it. Have the relief and pressure source through a tee on the other connection.

As Grant said, heat it with a torch. The angle-fitting has a cement on the threads that heat will loosen. I have 2 HF pots. I took that fitting off the tube and screwed it into the bottom of the lid. I put a ball valve and quick-connect fitting on the top. That way, when I fill the pot, the air blows against the side of the pot rather than down into the casting.

I got mine to unthread but I had to really put the arm to it!

Eric and Grant; Thanks! I used the torch, but only the top of the fitting came off. I figured it would be threaded down into the feeder tube. The male threads on the exposed socket in the top of the feeder tube don't look like a standard 1/4" thread and are much smaller than the 3/8" threaded pieces I have. I already attached a quick connect to a shut-off valve and the regulator. I want to see if it is really a 1/4" connector. If it isn't, I may just plug the tube and do like you did.

Well; The threaded part in the top of the pot ISN'T a standard thread! The pot on display in the store has a 3/8 thread, but this pot is slightly different.
Let the buyer beware!

A heat gun or torch will work, the (high temp) heat gun being the safer and less potentially destructive of the two. I think HF has them on sale regularly for around 10 bucks, a handy thing to have for all sorts of applications.

Or you could probably just put the whole thing in an oven for a while if you don't have either.

Just drill, thread and plug if you don't want to restore it to original condition someday. You can re thread to any thread you desire easily enough, or even just put a bolt with a gasket through the hole and tighten with a nut on the other side.

I drilled it to be super thin, then broke it with the pipe wrench. Then retapped it.
But I guess it would have been easier to use a torch.
