This Eaton Aeroquip adapter is a good choice for brake systems, connecting a -03 Male JIC 37-degree flare to a 3/8-24 Female 42-degree inverted flare. Just double-check those sizes against your truck's lines to be sure.

got a brake line with a 3/8-24 inverted flare on it. is this the piece that’ll adapt it over to a -03 JIC?

Question by: Hank B on Feb 12, 2026, 7:36 PM

For that hookup, you’re in the right lane. One side is a -03 male JIC with a 37 degree flare, and the other side is a 3/8-24 female with a 42 degree inverted flare, all in a straight adapter.
