Awesome, thank you! A thing of beauty

And here is a link to @Bettatail s step-by-step leak test, to walk you through evaluating a used regulator before starting the build, and the seals on your fittings after!

(Also for those of us who suck with Teflon tape I have had excellent results using this Loctite 545 thread sealant





Not to be confused with red threadlocker Loctite makes a lot of products, 545 specifically is the high pressure sealant designed to fill up the threads. Instructions are on the package )

As a side note, @Bettatail makes amazing regulator packages of high-end, buy-it-for-life regulators for this hobby.

Both of my journal tanks utilize his regulators, and always will. Thanks @Bettatail!

a good condition Concoa 312 double stage regulator, not a stainless steel bar stock, but a hard chrome plated and stainless steel diaphragm, at this price it is a rare deal.

good luck.

Used, the black plastic dial has a crack leading from the small hex screw keeping it tight on the internal rod (possibly from overtightening), but still functionally operates (turning it shows progressively exposed 0-4-8-12-16).

Looks like they have multiple listings for regulators with your name attached.

You're right it probably is an AI bot generated listing, probably scraped your name from TPT

You should report each one of these as a false listing to eBay You should have standing to claim intellectually property infringement, if not a copyright infringement.

I reported this one, but it'll have more impact coming from you
