Steel Adapter, 1-1/16-12 Male SAE O-Ring Boss (Straight Thread O-Ring) To 1-1/16-12 Male JIC 37 deg Flare, 45 deg Elbow

On the JIC side, it is a 1-1/16-12 male SAE 37 degree flare with a 0.75 inch tube OD callout, so it matches the common 3/4 tube JIC sizing. The other end is a 1-1/16-12 male SAE O-Ring Boss, so you would need a female ORB port on the mating part.

For clearance work, it gives you a 45 degree elbow, so the two ends are not in a straight line.

Absolutely. Its applications include marine and military uses, along with chemical and food processing.

That's what this one handles. One end is a 1-1/16-12 male SAE O-ring boss, the other is a 1-1/16-12 male JIC 37 degree flare, and the body sits at a 45 degree elbow. Both thread sizes are the same dash-12, so you're not reducing anything in the process. It's part of Eaton Aeroquip's 2061 series, built from steel, and carries catalog number C1AZ24 if you need to cross-reference it against any shop documentation.
