    As I posted over at TPT:

    You just need an appropriately sized plug. You should be able to find this at any hardware store.

    For your solenoid, there may be several issues:

    There could be...

    As oldpunk mentioned, I would look for leaks, as that would be my first suspicion as well.

    For your second part, gas is supposed to stop flowing through the solenoid when it is unpowered. I assume...

    I also use nylon, as they are relatively cheap. I can also torque them down tightly without risking them cracking (as is the case with Permaseals).

    It is generally recommended to change nylon...

    Only if perhaps you are looking for something else.

    New "old" stock (as it is sometimes known) is fine.

    For a larger aquarium such as yours, you may want to try the medium flow rate needle valves. Though, I have used a low flow model for a 90 gallon before as well (though not Swagelok).

    This idea has been proposed before over at the Planted Tank; I am not sure what came out of it, if anything, but you may want to take a look over there yourself.

    The flow meter is probably like the low pressure gauge on regulators. However, as their name implies, rather than measuring the pressure, they just measure the flow rate of a gas (think of CO2 and...

    I personally would not recommend any of those made in China/Asia "needle" valves. They seem to be floaty and difficult to stabilize.

    I would invest in a better valve.

    Both could cause problems.

    This is good. These adapters will convert from the tube fitting to the standard 1/8" NPT (male). You can just use a standard hose barb adapter (that screws into a 1/8" male NPT end).

    Not sure...

    The first metering valve reminds me of a SS2-A

    The second one has the model number printed on the side.

    (If the first one is the SS2-A), then both are usable.

    They use tube fittings - you...

    Yes, it will.

    Just make sure you get the correct power supply.

    All of this would be supposition at best. I have never seen a cylinder (over)filled to the point where the pressure release valve failed and caused a cylinder explosion.

    The pressure release valve...

    I would also be unsatisfied with these results.

    You are showing a 50% loss after 10 hours, which is a significant amount.

    I would stick with 1/8" for less of a headache, though some people use 1/4" parts since most of their parts are in that size and converting back and forth would not make sense.

    Tubing works as...

    Just replace the CGA540 nut and nipple with a CGA320 and you'll be good to go.

    In terms of post body kits, as Matt F. mentioned, I would also avoid tube fittings, since it will be cleaner without...

    I think it could be used.

    There is no indication of what CGA nipple it has though, so you may have to replace it.

    I was under the impression that yellow teflon tape is double density teflon and is just colour coded for gas lines.

    It seems that it is generally used on larger NPT threads; for our purposes, I...

    It is up to you :)

    I have yet to get a quote for my two DOAs, if the repair parts are cheap, I can fix it myself (or if the service repair is fairly reasonable), and it can still be a good deal.

    The Matheson Series 8 are dual stage regulators. There is not much documentation regarding them because they are very old (1960s or so?)



    However, if you can get a working unit, they are...

    Hey LeftC, you'll be out of the nursing home sooner than you think. Stay strong!

    Bettatail, thanks for the work; it's too bad shipping costs to Canada went up so much due to the USPS increase.

    If this ever happened, I'd want to join too :)

    Too bad I'm all the way over in Canada (and now that USPS has increased its shipping prices for flat rate boxes as well...)
