Re: 9/16” NPT --> plug 'n cool

Citation de "Beun"
Is it possible to fit a plug & cool connection to a 9/16” NPT threat?
Depends on who made the mating thread as not all 9/16 NPT threads are the same. All "PLug & Cool" connectors are 6mm ID/8mm OD push-fits. You can get push-fits to fit 1/4 NPT (not through AC though) as I think you are confusing the terms. A 1/4 NPT thread is actually a 9/16-18 tapered pipe thread made to USA National standards. Legris, Parker, and Norgren make these among other manufacturers. Plug & Cool uses 1/8 & 1/4 BSPP (G 1/8 & G1/4) threads which stands for British Standard Parallel Pipe. Some people have done what you are asking by wrapping a whole gob of pipe tape on the threads before screwing it in. Not recommended :-/ Best to get the right thread for the right job

I gave up on this exact question after spending about £50 trying various "multifit" p&c barbs.
Used a 3/8 9/16-18 normal barb which was a nice snug fit for my 10mm OD/8mm ID tubing.
Where can I find companies that deal with these type of fittings, I would really like to use a Danger Den Maze4 chipset block with my AC loop, but Danger Den use 9/16" thread sizes.

Am I gathering that you are trying to interface a Danger Den Fillport to your Aquatube? I used an AC 3/8" barb with 1/8 BSPP added to the back of my Aquatube and the tubing goes to my DD Fillport. I did have to take off that silver screen off the Aquastream because it was getting in the way. It ended up loooking a lot better in the long run though. ;D
Now after doing that I have been considering doing some other way of mating that Fillport to my circuit. I am looking around for what is called an "unequal T" push-fit fitting. Essentially the top of the "T" would be for standard 8/6mm "Plug & Cool" tubing. The bottom of the "T" would be some tube size so that I can directly connect the Fillport. Thus I would have an easier way of introducing fluids into my system through one of the return lines coming back into the Aquatube.

Sounds perfect. Do you have pictures by any chance?
You know that there is an even easier way of doing things... using simple stock parts.
Firstly, buy a G1/8 thread 10mm barb (that's 3/8" sized) and then screw it into your Aquatube..
then, buy a 3/8" sized Danger Den Fillport.
Lastly, get some 3/8" tubing and connect.
If you don't want to use 3/8" tubing, then you'll have a harder time looking for (but it is available) a 3/8" female to G1/4 (equivalent) female reducer and then screw a plug & cool fitting on one end and the DD Fillport on the other.

The clear tube goes to the Danger Den Fillport from the AC 3/8 barb x 1/8 BSPP fitting. You can see more of my project Feeding Frenzy here. I also keep a duplicate worklog on the [H]ardForum as well.

Dangerden is currently moving to 9/16-18 (aka UNF, fine thread). UNF is parrallel while NPT is tapered.
9/16-18 IS a *tapered* thread. Thats why there are two numbers (16 and 1
at the end, to give the diameter at the largest and smallest points.

Sorry, but that is wrong. 9/16 is the size in fractional inches. The 18 part is the threads per inch. The DD part is a standard UNF (United National Fine) thread pitch which is straight and it is not anyway like a BSPP thread spec. They just added an o-ring to the barb and it fits kinda okay on a NPT female thread. A 1/4 NPT (National Pipe Thread) is a tapered 9/16-18 thread spec though it is never called 9/16-18 because it would be too confusing.
Do yourself a favor and use a BSPP as they don't leak.

I am using 1/4 NPT on my rad and it doesnt leak, its sealed using pure sillicone adhesive sealant (no way it will leak, the tubing will burst well before the thread leaks).
You used 1/4 NPT on a BSPP threaded radiator? :o
