Hey guys, it's been a while. I am finally getting my workshop together after 5 years. I'm almost done and looking to set up my booth and compressor. My question is this, what can I do to put 1 hose with a quick connect MAC valve that will handle Iwata, Paasche, and Badger? HELP!!

If I understand you correctly you would just need a male end on all three brushes and the one female end on the hose, the threads may be different for each airbrush requiring you to get a fitting for each specific brush but the quick connect part should be the same regardless.

I buy all thease connectors,also the fine adjust quick connect with 3 male,for few bucks from http://www.aliexpress.com

thease is ship with 3 male not 2

If there is a branch of Harbor Freight Tools near you, you might try there. They have all manner of connectors for air hoses, and cheap

Thanks for the help guys. i should've been more clear, sorry. I know the quick connect is universal, and Paasche being difficult needs its own fitting, will the Iwata and Badger need their own too or will the "universal" ones work? I have no idea what size male screw end is for each AB. Thanks again.

You need to buy male fittings specific to each airbrush as they
are all different but will all fit the female fitting which is
connected to the airhose.

Have a look here,scroll down and you will find the male connectors for your Iwata, Badger and Paasche.

I have no connection to this outfit just using it for
reference.

OK. Thx again. I hope only one more question. I am just going to go to a local plumbing supply house for the fittings, maybe I'll get lucky. Can anyone tell me what the sizes are for the 3 brands I said? I'm talking the threaded connection on actual airbrush....I am really not this stupid, I swear, but it's hard when the companies actual website offers ZERO specs....

Mike...you will not find those quick connect couplers at a plumbing shop.

They are available from airbrush supply stores and these are
designed to fit directly to the threads on your specific airbrushes.

No size required, you get one each designed to fit the specfic airbrush.

Here is another reputed outfit:

You need:

AD 9 for Iwata
AD19 for Badger
AD29 for Paasche

Badger use M5 size,Female M5 to male 1/8

you need a adapter like this one for your badger...
