Reusable Fitting for FBF A/C Hose, -06 Female O-Ring Pilot, -06 Hose, Straight With Charge Port

This Eaton Aeroquip fitting is specifically designed for FBF A/C hose.

Fit comes down to the dash sizes, and this one matches a -06 hose end for FBF A/C hose and uses a -06 female O-ring pilot connection on the other side.

Reusable in this context means the fitting is mechanically attached to the hose rather than crimped, so you can remove it and reinstall it on a replacement hose when the time comes. That's the whole point of the FBE1812 design. It's a legitimate feature, not just a label. Keep in mind it's built for FBF A/C hose in the -06 size, so you'd want to make sure any hose you're putting it on matches that spec.
