m00se Ok excellent - I think it's making sense now - someone put me onto Mem-Co out of NH today for the various nipples and elbows, too. Thank you all for your help!

go for it.

need a 1/8 npt hex nipple and a 1/8 npt male/male elbow, you can connect this metering valve between the solenoid and the bubble counter.

Ok, less insanity here today... ugh... So if I understand you correctly, you have the part that screws into the bottle-side of the valve. That would connect to the output of the solenoid. I would need a short tube threaded on both ends to do that, right? I think I have that! Let me know what you want for it OP.

Thank you

I searched Parker H3L and it didn't come up, DB. There's one for $75 + Shipping. Could you paste the item # for me?

Thanks!

The threaded port on the solenoid is doped up pretty good with white pipe dope.

I didn't put this unit together. I bought it from a guy off craigslist when he got out of planted tanks, so for me there is a bit of mystery purely because I didn't go through the steps of assembling it myself. So far it's worked well, I'm just not liking the look. It's functional as is...just ugly ;-)

m00se Thanks OldPunk...Lemme get out of this monkey suit (just got home) and I'll get back to you.

Will look there then. Thanks for the heads-up on the JBJs. The BC has no adapter. The barb piece is screwed into the bottom and has a rubber ring washer in there.

You would be better off getting the newer Fabco NV-55-18 (which has 1/8" female NPT ports). Alternatively, you could just get the stainless steel Parker H3L that is still available on eBay (also has 1/8" female NPT ports).

Thank you for your wisdom. I will educate myself more and make some decisions now.

The solenoid is the black box that is slightly to the left and above the regulator adjustment knob. There is a small wire that goes downwards from it as well. It is immediately before the Parker H3L metering valve and the 90 degree elbow.

Please feel free to correct me if I am wrong.

It looks like your solenoid has a hose fitting, which connects to a Fabco NV55 (with #10/32 to hose barb) fittings. This then goes to your bubble counter which also has a hose barb fitting?

I do sell complete systems, but if it is possible, better to build one yourself.
pm me for what you have so far, I will give you direction where to find the rest parts.

Bettatail build one yourself, good luck.
The second system was around $150 to build, you get a double stage system and all good parts, the metering valve is Parker H3L high precision stainless steel, $450 retail.
The first system cost much more to build but it is a full stainless steel, will last forever.
read oldpunk and darkblade's threads to learn about the basic, then you can put up a system yourself.
