Looking for an air chamber hose

I'm looking for what seems to be a special air hose... of course...

The standard one is:
3/8" I.D. Air Hose Assembly with 3/8" One Fixed-One Swivel Ends

The swivel then usually comes with an adapter and by default this adapter is for 3/8" mpt.



..however, I need the adapter to be 1/4" mpt.

I found 1/4" x 1/4" hoses in 3/8" diameter but that won't work because then the one fixed end is 1/4" mpt.

Haldex doesnt make what I am looking for, so I wouldnt mind buying the hose above but cant find these adapters I need.....

I believe they are bubble flair to mpt ?

 

Thanks...I got a line on these hoses, dirt cheap. I just need the correct bubble flare to npt...

 

That was my other thought.....

 

Yea I might try some dealers....but they can be spendy. ($20 or more for a $7 hose).

so...maybe I will keep looking for the bubble flare to NPT.
NAPA might carry or can get those.

After all, the fitting i need comes on a HALDEX cable....so SOMEONE must make it!
