Is the 3/8 a brake flare? If it is, then no. The 2 have a different sealing surface, for lack of a better word. AN is a 37* face, and the brake flare is 45*. Plus, it's a flare, it has a different fit. I know Speedway would have an adapter tee. Let me check back in quick with a picture of what I think you are talking about.

I take back what I wrote.....just get these, and screw them in the tee.

I don't know how much time I've spent researching and trying to find information on different fitting types: NPT, inverted flare, AN, metric bla bla bla. Its frustrating at times.....good luck!

-3 AN is 3/16"..

The AN is a National standard for the US Military Specifications (Air Force and Navy = AN). A AN size of -1 would be 1/16 and goes up in 1/16" increments

Try this as a FYI for that late night reading..

Remember that JIC 37deg fittings are compatible with AN fittings. Only differences:

1. JIC cost less
2. JIC are steel
3. AN thread form is, for example, 3/8-24-UNJ-3A with the "J" meaning an enlarged root-radius for high-reliability aircraft use.
