Steel Brake System Adapter, -04 Male JIC 37 deg Flare To 10mm x 1 Male Metric Flare, Straight

This steel adapter is designed to connect a -04 Male JIC 37-degree flare to a 10mm x 1 male metric flare, which is commonly found in brake systems.

That's what this adapter is built for. One end is a 10mm x 1 male metric flare and the other is a -04 male JIC 37-degree flare, so it bridges that metric-to-JIC gap without needing extra fittings or adapters in between. It's a straight configuration, so no angle changes in the line routing. Eaton Aeroquip makes it from steel, so it'll hold up in a working brake system without giving you corrosion headaches down the road.
