Steel Adapter, 3/4-16 Male SAE O-Ring Boss (Straight Thread O-Ring) To 1-1/16-12 Male JIC 37 deg Flare, 90 deg Elbow

For that exact connection, yes. One end is a 3/4-16 male SAE O-Ring Boss thread, which seats against the boss port using an O-ring seal rather than a flare. The other end is a 1-1/16-12 male JIC 37 degree flare, so it'll mate with a standard female JIC swivel fitting on your hose or line. The 90 degree elbow body handles the direction change right at the fitting, which saves you from bending the hose or fabricating an offset somewhere else in the run.

You’re looking at an Eaton Aeroquip 2062 Series 90 degree elbow adapter with a 3/4-16 male SAE O-Ring Boss on one end and a 1-1/16-12 male JIC 37 degree flare on the other. If those are the two thread styles and sizes you need to join, this part matches that combination.
