Our take on the Radium Engineering AN ORB to NPT Adapter Fittings (20-0290)

A straight aluminum adapter that converts an O-ring boss (ORB) port to a male -6 AN flare, with 5/16 in. female threads on the port side. Radium builds it from anodized aluminum, so it is light and resists corrosion, and the ORB side is meant to seal on an FKM O-ring rated for oil and fuel. It suits anyone plumbing a fuel, oil or power-steering system that already uses a standard ORB port. Compared with generic brass or steel AN adapters, it is lighter and better finished, but it is a single fitting sold on its own, with no O-ring in the box and no swivel, so you supply the seal and plan the routing around a fixed angle.

Pros
  • Anodized aluminum is light and resists corrosion
  • FKM O-ring spec suits oil and fuel
  • Straight -6 AN male flare on one end, 5/16 in. female ORB on the other
  • Radium part number 20-0290 makes replacement easy to source
  • Black and green finish looks tidy in an engine bay
Cons
  • O-ring is not included, so you must supply the correct FKM seal
  • No swivel, so the angle is fixed once tightened
  • Sold individually, so multi-port jobs need several
  • Aluminum threads are softer than steel and easy to cross-thread

Questions and answers

What does this adapter connect?
A 5/16 in. female ORB port to a male -6 AN flare line. It is straight, with no angle or swivel.
Is the O-ring included?
No. The listing says O-rings are not included, so buy an FKM O-ring sized for the ORB port you are sealing.
Will it work with fuel and oil?
Radium specifies FKM O-rings for all oil and fuel types, so pair it with an FKM seal for those fluids.
Is it a swivel fitting?
No. It is a fixed straight adapter, so the hose end angle is set once the fitting is tightened.
How many fittings come in one order?
One. It is sold individually, so count your ports before ordering.
