Our take on the Radium Engineering Fitting 6AN ORB to 5/16 BARB

This is a Radium Engineering adapter fitting that converts a 6AN ORB (O-ring boss) port to a 5/16-inch hose barb. It is aimed at people plumbing fuel systems: Radium fuel rails, surge tanks and fuel pressure regulators all use ORB ports, and this lets you run push-on 5/16-inch rubber or soft hose off one. It is a small, purpose-built part rather than a universal adapter, so check your port thread and hose size before ordering. Compared with generic brass barb adapters, it is made to Radium's fuel-system tolerances and finishes, but it only fits 6AN ORB ports, not the larger 8AN size.

Pros
  • Converts a 6AN ORB port to a 5/16-inch hose barb in one piece
  • Matches the ORB ports on Radium fuel rails, surge tanks and regulators
  • Aluminum construction suited to fuel systems
  • Compact, so it fits tight engine-bay spaces
  • Simple push-on hose connection with a clamp
Cons
  • Fits only 6AN ORB ports, not 8AN or other thread sizes
  • 5/16-inch barb limits you to that hose size
  • Not for high-pressure braided line without proper clamps
  • O-ring for the ORB side may not be included
  • Easy to order the wrong AN size

Questions and answers

What does this fitting adapt?
It takes a 6AN ORB (O-ring boss) port and gives you a 5/16-inch hose barb. The ORB side seals with an O-ring against the port face.
Will it fit my Radium fuel rail or regulator?
It fits Radium parts that use a 6AN ORB port, which covers many fuel rails, surge tanks and fuel pressure regulators. Check your part's port size first, since some Radium ports are 8AN ORB.
Can I use it with braided hose?
The barb is sized for 5/16-inch push-on hose, typically rubber or soft line held with a clamp. For high-pressure braided line, use a proper AN hose end instead.
Is an O-ring included?
The fitting is the adapter itself; confirm whether an O-ring comes with it. ORB ports need a fuel-compatible O-ring to seal.
What thread is the ORB side?
It is a 6AN ORB port, which is a straight thread with an O-ring seal, not a tapered pipe thread. Do not substitute NPT.
