Product Questions & Answers

got a brake line setup with a -04 JIC male on one side. will this adapter let me hook into a 3/8-24 inverted flare port without any goofy angles?
Question by: Wayne C on Oct 10, 2025, 1:11 PM
Built for brake system hookups, it bridges a -04 male JIC 37 degree flare end over to a 3/8-24 male 42 degree inverted flare end in a straight body, so you are converting both the thread style and the flare type without adding a bend.

Will this adapter work to hook up new brake lines on my '67 Mustang?
Question by: Shawn T on Dec 17, 2025, 5:54 PM
This adapter is designed to provide the correct connection between -04 male JIC 37° flare fittings and 3/8-24 male 42° inverted flare fittings, which are often found on automotive brake lines.

got a brake line on an older rig that runs 3/8-24 inverted flare on one end and JIC on the other, this the right adapter to bridge that gap?
Question by: Dale J on Oct 24, 2025, 4:10 PM
That's exactly what this fitting is built for. One end is a -04 male JIC with a 37 degree flare, and the other is a 3/8-24 male with a 42 degree inverted flare. Those two thread and flare configurations show up together pretty often in brake line work where hydraulic and automotive hardware meet at the same junction. The straight body keeps things tidy in tight spaces too, so you're not fighting the routing.
