fitting's got female ends on both sides, right? just want to make sure before i order it for a brake line repair
Answer by: Customer Support on Feb 9, 2026, 6:58 AM
Correct on both counts. The 302X6 has female-to-female connectivity with 42-degree inverted flare ends, and the tube O.D. is 0.375 inches, which lines up with standard SAE brake line fittings. It works as a union, so you're joining two lines together rather than stepping down or changing thread types.

got a 3/8 hard line with an inverted flare, is this the little union that ties two female ends together?
Answer by: Customer Support on Jul 28, 2025, 9:35 AM
It’s a female to female 42 degree inverted flare union made for 0.375 inch tube O.D. with SAE end types, so it’s meant to join two matching male inverted flare tube ends on 3/8 inch line.
