Yup, like these, they come in different barb sizes, but all the same 1/4" flare:Commonly referred to as "1/4 inch flare" here...
You are correct, there are many subtypes of flare fittings that aren't perfectly interchangeable due to threading specs. That said, I have not run into any problems in that regard wrt brewery plumbing...
My tactic has been to order from places that specialize in brew stuff, assuming their parts are compatible (i.e. Flare Fittings : The CHI Company, New and used beverage equipment for Homebrewing, Home winemaking, Soda systems and used Pepsi vending equipment),
Do either of you know of a "brewery plumbing 1/4" Female Flare" x 1/4" MPT adapter?
Using a washer a -4 JIC plug sealed against a FFL at 60psi. Threads are the same, end angle looks the same. Think it's safe to say the the "flare fittings" commonly sold at brewery supplies for kegging -4 JIC fittings.
Cheers! (Our Aussie brethren are so advanced wrt beer tubing, fittings, faucets. WTH? )
Do you need the swivel? If not the $8 one from brewers hardware I linked above will work
The swivel is nice. But if I couldn't get it, I'd try the one from brewers hardware, which (I assume) is also JIC.
Sounds like you want to connect the adapter straight to the keg threads but you could get a pin lock QD with a flare connection as a fall back. Take the poppet out if you wanted to increase the flow.I have old Firestone Spartanburg Pin Lock kegs with 9/16"-18 post threads. I'm looking for an adapter to 1/4" male flare.
All I can find from homebrew vendors are for Cornelius kegs with 19/32"-18 post threads. I did check with CHICompany and they could make it work combining 3 fittings. Not ideal and total is more than twice the cost of the one below.
Will this work?
.
The fermenter has a racking arm and I pressure transfer from the fermenter to the keg. I currently use a QD but if dryhopping in the fermenter, the QD clogs. The poppet is needed to depress the stem in the QD to allow liquid to flow.Sounds like you want to connect the adapter straight to the keg threads but you could get a pin lock QD with a flare connection as a fall back.

The fitting on Amazon is stainless steel.I wonder if there is any concern about the plating of hydraulic fittings vs. (presumably) a fitting targeted to food/beverage use? Are not the 1/4" MFL/FFL fittings typ. stainless steel (other than perhaps a plastic flare cone or seal washer)?
OK. So you want the poppets out of the way to pressure transfer and you are dry hopping in the fermenter. But if you take the keg post off, how will the keg be sealed after the transfer? You may already have that part solved just not seeing it.The fermenter has a racking arm and I pressure transfer from the fermenter to the keg.

Yes and yesWhatever you put on the keg threads has to seal by compressing an o-ring on a dip tube (gas or liquid). I don't know if that adapter will. It will also need a flare washer on the other end.
This is what currently do:OK. So you want the poppets out of the way to pressure transfer and you are dry hopping in the fermenter. But if you take the keg post off, how will the keg be sealed after the transfer? You may already have that part solved just not seeing it.
This is what currently do:
Flush and pressurize the sanitized kegs and chill overnight.
Connect tubing between racking arm ball valve and keg beverage out with long dip tube
Release keg pressure using PRV in keg lid leaving keg full of CO2.
Connect CO2 to lid of fermenter and pressurize to about 3 psi bursts.
Open racking arm ball valve and beer is pushed to the keg from the bottom up while expelling CO2 out the PRV.
When keg is full, close ball valve and the PRV
The keg headspace is still CO2 but not under pressure.
Remove flare fitting and screw on post.
Pressurize to 12 psi CO2 via gas in.
I just want to replace the keg beverage out post/QD with the flare adapter. I have a Cornelius keg with the 19/32"-18 flare adapter and it works fine but almost all of kegs are Firestone 9/16"-18. All I need is a 9/16"-18 flare adapter. My basic question in the 1/4" Male JIC end of the Amazon fitting work with a swivel nut?
Yes it will. I'm not a fan of wrenching connections on and off for transfers and the bore of a flare is only marginally larger than the opening though the poppet so I'm not really convinced it's worth it.
I agree, but right now I sometimes have to stop mid-transfer to disassemble the QD and/or the keg post and poppet to clear the dry hop debris. I was assuming a straight shot flow through the flare would alleviate that with one fitting swap at the end.
The racking arm just has a ball valve.How about a medium coarse screen on your racking port valve first?
