For a -12 one wire braid hose, this fitting is the reusable two-piece style made for that setup, with a reduced bore design. The connection end is a 1-1/16-12 female JIC 37 degree flare swivel.

Reusable two-piece fittings are built exactly for that kind of flexibility. The socket and nipple separate, so you can remove the fitting from one hose end and reinstall it on a replacement hose without needing a new fitting each time. That makes them a practical choice when downtime has to stay short and you want to keep spare parts costs down.
