Maybe. I don't have one on hand.
I filed down two sides of the nipple so my vice will hold it again.
It's currently locked in the vice and no amount of strength will move it.
I tried putting a small piece of 2x4 against it and hitting the other end of the 2x4 with a rubber mallet and that won't break it loose either.

I have a heat gun and vice at the office. Maybe that will help.

Use a monkey wrench and a vise. Dont apply any heat to the regulator. The working temperature on these regulators are under 150F or so.

ok, i'll try that today.
I'm afraid of snapping it in half with the amount of force I'm applying.

I just had to spend $600 on a new Reeflo pump when I snapped the main shaft while trying to remove the impeller that was seized after 2.5 years of use.

ok, the big pipe wrench and vise trick worked.
But now I know why I was having so much trouble.
I haven't tried threading on the new nipple yet.

Oh that doesnt look good. Try to fix the threads with a taper. Wrap extra teflon to the cga320 nipple or you will have a leak.

How to build a CO2 regulator for your calcium reactor.

Here's a Hoke 1300 inline valve. It has a 1/4 tube connection so you dont need the swagelok adaptor. Just connect your 1/4 co2 tube directly to the valve.
Ebay item
381181399173

Setup will look like this

Alan, what is the knob with 10-15 and one lines on it?

Corey that's the swagelok vernier handle. Each company has its own vernier handle to fit with a specific metering valve in the family.

Alan,

Do I need that fitting coming from the bottom and the second valve is that just a metering valve if it is should I get a different one or use that one

It's a metering valve to precisely adjust your c02 entering the reactor. It's a must for me now, I didn't realise how crappy the one on the Milwaukee is compared to using this one.. Night and day when it comes to bubble adjustment..

Here's the 22 series needle valve. It's a rare needle valve with a metal vernier handle. It will work nicely with out application.

That is not a metering valve. It's a stop valve. You should remove it. Please look at my first post. The stop valve is not needed. That fitting sticking out from the bottom is a relieve valve. You can leave it there or cap the hole with a 1/4 npt plug. A full Co2 tank is only 800psi. A relieve valve is not required.

So how much pressure can you have going into the Reactor. I have an MTC ProCal Ca reactor and it has a pressure gauge on the first chamber, when running it reads about 3-4 psi inside the unit. I have the CO2 gauge reading at 30psi and I still have a difficult time controlling the bubbles (meaning making fine adjustments say 40 bpm to 50 bpm).

Really? I don't have any problem fine tuning with it. I only keep my regulator around 20 psi though. Perhaps you have it opened too far?

Maybe, I had been thinking that a higher PSI would make it more stable. But your right, maybe it is the other way. I know it takes about 5 minutes from when the solenoid clicks on till CO2 starts to come out of the bubble counter, so I was thinking I did not have enough pressure to overcome the internal psi of the reactor and the check valve.

I was speaking more to the metering valve being open too much vs the regulator. I don't think 30 sounds excessively high at all. Maybe back it off to 20. That being said, 5 min lag from the solenoid being opened to CO2 hitting your bubble counter seems really excessive to me. Mine is within a few seconds. Where is your check valve located. Perhaps it has become fouled and is impeding CO2 release? I use two check valves, one closer to the bubble counter as well as loop the line to reduce any potential water back flow within the CO2 line. I know a lot of people will even use 3 check valves as they are cheap and regulators are expensive.
