Problems converting regulator to CGA 320

I recently just purchased a regulator from eBay and I'm having a heck of a time trying to take off the CGA 580 nipple that came standard with it. I've already stripped a bit off the nipple. Anyone have any suggestions of how I can take this thing off?

Put the regulator body in a vice protected by something soft to avoid marring it. Get a set of vice grips clamped hard on the thing you've already stripped.

Use force.

I had to really crank on exactly the same part. Finally got it off.

BTW, if you want to remove the on/off valve on the other side you'll need to remove the low pressure gauge to provide clearance.

good luck

Thanks for the tips Jim! I will definitely give it another try. It seems that there's some sort of loctite adhesive on the threads itself.

x2 on the vice and vise grips.

You could also use some penetrating oil or a propane torch..... just not at the same time

As I recall I was able to unscrew the nipple on my regulator by holding the body with a big adjustable wrench, but I don't remember how I did that. I used a small pipe wrench on the nipple. It was actually pretty easy once I figured out how to hold it.

How can I remove Loctite Threadlockers?

Blue: Can be removed with hand tools
Red: Apply heat to remove
Green: Apply heat to remove

Nasty - organic solvents might help.

I was sure mine had some sort of threadlocker but it was just on really tight with teflon tape.

Nipples have to be installed with a sealant, not a thread locker. The sealant is necessary to stop leakage through the threads. But, some sealants do get hard and can be hard to break loose.

I had recently got a sweet deal on a compact uniweld regulator. My thought was to "convert" the input from CGA 320 to 1/8" to run a paintball tank through the ASA. I had these materials so I decided to try that instead of ordering a CGA 320 to PB tank adapter.
What I did was, using a bench vise and a pipe wrench, broke the 1/4" brass nipple off about 3 threads INSIDE the regulator body. OK I thought...I'll use a "bolt-out" bit and get it out of there. I got the bolt-out bit seated real good, but upon trying to extract the nipple, the bolt-out bit broke! My goodness! That's tempered carbon steel. My thoughts were there must be some kind of sealant, lock-tite or something in there. No way would the mere tightening alone of that nipple create a strong enough bond to break that bolt-out bit.

It could.... NPT threads are tapered, and if wedged all the way in, that is a tight, tight fit.

It was sooo sad! I do recall another person telling me about the tapered threads as well...never thought of that. I did have success with the a victor, as well as an older concoa, so I know it can be done. All fittings on the uniweld model that broke were stubborn. I really want to salvage the 1-1/2" gauges off the unit but they are stubborn as well. The main obstacle with that unit is positioning in the vise. I thought about stripping it all the way down to get a better bite on it but rebuilding a pressure regulator is not yet within my realm of capability.

As long as you don't want to salvage the nipple on their, file some flats on it so you can get a better grip on it.

Be careful with how much force you use. Ive sheered off a CGA520 nipple in a regulator while trying to remove it.
