Steel Adapter, 9/16-18 Male JIC 37 deg Flare To 9/16-18 Male JIC 37 deg Flare, 90 deg Elbow Bulkhead

For a right angle pass-through, this adapter is a 90 degree elbow bulkhead with male JIC 37 degree flare ends on both sides, and both threads are 9/16-18.

For a bulkhead mount with a 90 degree turn, this is exactly what you'd reach for. Both ends are 9/16-18 Male JIC 37 degree flare, so the line connects on either side of the panel without needing an additional fitting to make the angle work. The elbow handles the direction change right at the bulkhead, which keeps things cleaner and cuts down on extra hardware in tight spots.
