amazing, when you asked whether to get this reg, didn't know the condition of this beast.
Even it is a chrome plated, this thing is $500+ retail price, the same condition as the one in the picture, good buy!

Now I am drooling all over, :P

Here is a system, built a while ago, with identical regulator.

There is a used good working concoa 312 on there right now for 40 free shipping

i saw the used concoa on ebay, however just curious how do you know its a 'good working' one? did you by chance interact with the seller? its listed as used sold as is... i guess for the price, you just roll the dice?

The guy quoted me 600+, of course I didn't believe him. Is there a way to tell if it's chrome plated or Stainless Steel? Visually speaking I mean, would chrome be way more shinny?
Is the regulator in your picture Stainless Steel or Chrome?

A 3120 Series is nickle plated brass.

http://www.mathesongas.com/pdfs/prod...-Regulator.pdf

Op's - to answer your question, yes, the chrome ones are lot shinier (in general) than most stainless. Some of the stainless ones have been more polished and are pretty darn shiny. Most stainless regs have what I would consider a 'brushed' look. Nickle plating is pretty close to the appearance of stainless steal.

Let's just pretend it's Stainless Stain. How come Bettatail's 3120 series regulator looks less shinny? I know my gauges for sure is not SS, wish I could see the same for my regulator.
Thanks for the correction, my ego and self-esteem needed that.

Any recommendation for a good solenoid? I would prefer it not to be hot, and not in need of rewiring.

It is the same model in the picture, took the picture without auto/enhence settings to show the most realistic look, so it wasn't as "shiny" as yours.

As oldpunk mentioned, all 3120 model are plated, mantheson 3180 or 9400 are true Stainless, $800+ retail though.

Must be my iPhone 4 camera, makes everything pretty shinny. Here is a chrome CGA 320 nut next to it.




Edit: Anyone know about these panel mounts? You can have a row of regulators and remove the adjustment knob so no one else can mess with them. Matheson has a pdf guide for this. So according to them, you can remove the knob by loosing the hex nut. Set it at a pressure that you want and hold it with a flat head screw driver. Once the knob removed, you won't have to worry about someone messing around with the thing.

But then again....you won't have an awesome blue knob with a Matheson sticker on the cap.

Are you really considering panel mounting your regulator? That will pretty much cause you to need to run a line to cylinder instead of just going right from cylinder to regulator. Running a high pressure line can get costly.

+1. Not sure why you would consider panel mounting when just cylinder mounting is perfectly fine.

good to try, but is there any need to make the system stationary underneath your fish tank, if your fish tank is not an oversize one?

besides front bracket panel mount in your picture, there are back bracket mount or back support mount(mainly for single stage), and manifold back support mount.

swagelok compression tube fittings and swagelok braided air hose, or parker parflex hose, are good to connect between the regulator and co2 tank. These high pressure hose or fittings are quit expensive, anyway, you can get a $500+ matheson 3120 regulator for $100, look hard enough you will find yourself the right braided hose and compression fitting at really low cost.



this is one of the typical mounting spare set(manifold back support mount), I've showed it here or there, and actually it is a set I save for myself, once the new stand for the fish tank is built, this mount set will be utilized. several other back bracket mount kits available though, don't have the picture.

I don't have the kind of cash for that.


Just thought I throw that info out there. If anyone was wondering about the adjustable knob, it is removable - for Matheson anyways.

Anyways, what you guys do with your CGA 580 connection or whatever came with your regulator? Do you just sell it?
