Blue Anodized Aluminum Adapter (AN 832), -03 Male JIC 37 deg Flare To -03 Male JIC 37 deg Flare, Straight Bulkhead

Straight into the bulkhead is exactly what it's built for. Both ends carry -03 Male JIC 37 degree flare connections, so you're passing the same size line clean through a panel without needing any intermediate hardware or bracket. The aluminum body keeps weight low, and the blue anodizing gives it a little extra surface protection. Just make sure your bulkhead hole is prepped for the fitting diameter and you're good to go.

For a straight pass-through, it fits the job. It is a straight bulkhead adapter with -03 male JIC 37 degree flare on both ends, so you can connect a -03 JIC line on each side of the bulkhead.
