For a properly planned performance build, the Radium Engineering 6AN Orb Bulkhead 3/8in SAE Male TO 5/16in Barb connects 6AN Orb Bulkhead 3/8in SAE Male to 5/16in Barb, giving the system a direct transition between the two connection standards. That keeps the plumbing compact and serviceable while avoiding a stack of extra adapters in a fuel, oil, or other compatible fluid system.

The configuration shown here uses 6AN Orb AN/ORB sizing and a 3/8in SAE Male SAE connection, making exact connection and component matching important during installation. Match both connection standards exactly and use the correct sealing method for the thread type being installed.
