Can anyone tell me what type of adapter this is? The male part connects to the radiator the female to the transmission supply line .

<a href="http://s1288.photobucket.com/user/richuncle_car/media/photo_zps2f485761.jpg.html" target="_blank"><img src="http://i1288.photobucket.com/albums/b491/richuncle_car/photo_zps2f485761.jpg" border="0" alt=" photo photo_zps2f485761.jpg"/></a>

Full story...I changed out my radiator and I had to move these adapters over. They had some crud on the threads that wouldn't come off, so of course one of them ends up leaking. I went to Napa and purchased a 1/4 NPT (male) to 5/16 inverted flare (female) fitting (brass) and the NPT part was right but the inverted flare was not. The actual steel transmission tubing flared end would go down fine, but the nut was too big for the female threads. Even if that was correct, the nut on the transmission line seemed to be long (the first quarter inch has no threads). The brass adapter I got from Napa was shorter than the original and would not have allowed for that extra length.

So I put some teflon tape on the original fitting (hope that wasn't a horrible move) and tightened it down more than I did the first time. I don't think I have a leak now but can someone more knowledgeable about tubing fill me in on what I need?

Hopefully you didn't mess up the threads on the radiator tank fitting..

Anyways..The size is 1/2-20 FEMALE X 1/4 NPT MALE..
The side with the 1/2-20 must be a female inverted flare..The 1/4 NPT is the side that inserts into the radiator tank fitting..

Here's a link to a replacement you can pick up at AutoZone--->>Dorman 47155



Rayo..
