Blue Anodized Aluminum Adapter (AN 919), -10 Male JIC 37 deg Flare To -06 Male JIC 37 deg Flare, Straight

For stepping down between two JIC 37 degree flare sizes, this one matches that job. It has a -10 male JIC 37 degree flare on one end and a -06 male JIC 37 degree flare on the other, in a straight configuration.

That's what this adapter is built for. One end is -10 male JIC 37-degree flare, the other is -06 male JIC 37-degree flare, straight through. Both ends are male, so you'll be threading into female JIC fittings on each side. It's an Eaton Aeroquip part, SKU FBM2162, also listed under C1EB28 and FCM2162 if you're cross-referencing with another supplier.
