    And where have I seen that Victor 2-Stage Regulator CO2 rig they're using as an image on their website? Hmmm.

    You're Famous.

    I am planning on doing this also because I already have a couple of 1/4" MPT x 1/8" FPT reducer bushings laying around.

    Your suggestion will work just fine. Strength shouldn't be an issue.

    Here's what I would use for a regulator with it's output at 9 o'clock. I'd use a 1/4" x 1/8" reducing bushing and then a 1/8" hex nipple.

    Using a regulator with its output at 7 o'clock, there are several ways to do it. Coming out of the regulator, you could use any of these reducers:

    I told them that quite a few people are building regulator assemblies for aquarium use now. I sent them the link to this thread as an example. I didn't know that they were going to use my Avatar.

    I'm curious. Did freshwater systems carry the burkert solenoids before getting this batch of Buna seal units? I ask because I ordered a solenoid and din plug from them yesterday and am wondering if I will be getting the new one or will be getting an older style....

    I just re-did this regulator with more aesthetically pleasing fittings. The 3" nipple comming out of the regulator was too long when the coupling was attached. It looked unbalanced.

    I replaced it with a 2" nipple. Everything looks more compact and tight.

    To my knowledge, they never carried the 6011 Viton seal model. They do carry other Burkert products, though: http://www.freshwatersystems.com/search2.aspx?page=1&keywords=Burkert&Search=Search

    You can forget the Sir part. I might deserve a good kick.

    Be sure to order one of the two LED cable plugs along with your solenoid.

    Are they asking about different buna-n "batches" of solenoids or "the older version" meaning Viton seal versus Buna-N.
    I don't think there are any "old batches" of BUna-N solenoids out there. Prior to Freshwater Systems carrying them, they were only special order with a 5-7 week lead time.
    If you're worried about having a Viton unit, it's easy to tell: they are a different part number.

    Thank you for pointing that out to me. I skimmed over it pretty quickly and don't see how I missed that they were both LEDs. Duh.

    I think that I might have to eat some crow because of something that I told you. So, take back the Duh for the time being. I might need to use it. :eek:

    Out of curiosity, is there any generally accepted wisdom here about what kind of tubing adapters to use? I wasn't expecting there to be such a wide variety. It looks like most people use the one that comes stock at the end of the JBJ bubble counters, but I'll be putting an adapter on to my Ideal needle valve and then running tubing to my DIY bubble counter. I've been looking through the McMaster-Carr sight, and there are like 6 different kinds... can anyone narrow down the alternatives for me?

    What is the inner diameter of the tubing that you will be using?

    If the ID is 1/8" and male thread that screws into the Ideal needle valve is 1/8" NPT, you can use either brass or plastic adapters.

    Heh, I actually haven't figured out the dimensions of the tubing yet; I'm still reading up on that (really not sure why something so supposedly simple as tubing needs to be so complicated; I still can't figure out what the final word is on that--size, material, etc.). But I figured I'd get the brass figured out and adjust the tubing dimension of the fitting once I decided on the tubing.

    BTW, where is the picture you posted from? There's nothing like that on McMaster-Carr; they only have a MPT with a tubing stem (which looks like a post with two channels across it). Do you find the barbed connectors generally better than the screw-on connectors at the top of the JBJ's?
