Blue Anodized Aluminum Adapter, -03 Male JIC 37 deg Flare To 1/8 Inch Male NPT, 45 deg Elbow

This adapter features a -03 Male JIC 37-degree flare on one end and a 1/8 inch Male NPT connection on the other.

For that kind of hookup, it matches what you described. It is a 45 degree elbow adapter with a -03 male JIC 37 degree flare on one end and a 1/8 inch male NPT on the other, so it lets you transition between those two thread types while turning the line 45 degrees.

That's exactly the kind of spot this fitting handles. One end is a -03 male JIC 37-degree flare, the other is 1/8 inch male NPT, and the 45-degree angle between them lets you redirect the line without stacking on extra adapters. The blue anodized aluminum construction holds up well to corrosion and wear, so it should give you a clean, reliable connection in that tight area.
