50lb Freon recovery unit tank help.

Unread postAuthor: warhead052 » Tue Apr 19, 2011 8:30 pm

I got a 50lb freon recover unit, and I was wondering what I needed to do to make it hold air. I will post a picture as soon as possible.


Edit, I just figured out its actually 25lbs... If its any consolation, I found the logo Wellington Canisters printed on the valves for it.

I guess I gotta figure it out... I may just take off the valves and put in my own tee and what not...

That's probably the best course of action. I have no idea what valves are on it, but you should try your best to make sure that you can get parts to match whatever threads are on the tank.

You may also want to add a drain plug on the bottom, or invert the tank if the valve is on the top. I don't recommend drilling any holes, but condensed water will rust your tank quickly.

At a minimum, coat the inside of the tank with several layers of rust proof paint.

You may be able to look up the tank on Wellington's site. Most likely the top is threaded with a 3/4 NPT thread. The valve will be screwed in very tight and the threads sealed with a sealant.

Doc, that's almost exactly what I have, just not bright orange.

Ramses, how the HELL would I be able to do that without cutting it open?

Tech, I looked it up yesterday, and apparently wellington doesn't have a site. The valve has one hell of alot of jb weld looking stuff on the threads, so its gonna take me awhile to get it off.


Lemme explain the valves. There are 2 connected to a Y piece, and one says vapor, the other says liquid. There are 1/8" flared threads to each one for a hose to hook up to, and at the back of the y there is another female threaded inlet or something. I am assuming you add like a vacuum or some thing to that part.

That is ALMOST exactly like it. Infact, mine is the same, but with a common propane tank shape. Any idea on how I can make it hold air? Or even how to GET air into it?

Ok sorry... Well it looks like there are two valves with threads. You can attach a quick connect or schrader to one side, and an air line to the other side. To fill, open the valve leading to the schrader/QC, then close it, open the air line and you're good to go!

Be careful of moisture buildup.

If you can unscrew the original valve, the opening in the tank is 3/4 inch pipe thread.

See the tank on the right. Original valve is removed and a 3/4 to 1/2 reducer and a 1/2 to 1/4 inch reducer make it compatible with 1/4 inch plumbing for air hoses, quick connects, gauges, etc.

The one on the far left is the same, I recognize the shape and the handles. Did it have the Y with two valves on it? Gun freak, I may try that.
