Radium Engineering 10AN ORB to 6AN Adapter vs Aeromotive ORB to AN Flare Adapter

Buy the Radium 14-0130 if you need to step a 10AN ORB port down to a 6AN hose end on a Radium fuel rail, filter, surge tank or catch can. Buy the Aeromotive 15605 if your port is 6AN ORB and you want a 90-degree turn to a 6AN flare. The Radium is a straight adapter in one size; the Aeromotive is a right-angle adapter in a different size. Both are black anodized aluminum with a FKM O-ring, and both are simple machined parts that owners rarely report failing. The Aeromotive carries a 5-out-of-5 rating from 10 ratings, a small sample.

  • Choose the Radium 14-0130 if your component has a 10AN ORB (7/8"-14) port and you need a straight 6AN male flare outlet for a standard AN hose end.
  • Choose the Aeromotive 15605 if your port is 6AN ORB and you need a 90-degree elbow to route a 6AN hose away from the fitting.

Questions and answers

Which one fits a Radium fuel rail?
The Radium 14-0130. Radium rails use 10AN ORB ports, and this adapter gives you a straight 6AN flare outlet. The Aeromotive 15605 is 6AN ORB and will not thread into a 10AN port.
Can I use the Aeromotive fitting on a 10AN ORB port?
No. Its O-ring end is 6AN ORB, which is smaller than a 10AN ORB (7/8"-14) port. You need the Radium adapter or a 10AN ORB to 6AN ORB reducer first.
Which is better for tight engine bays?
The Aeromotive 15605, because its 90-degree bend turns the hose immediately. The Radium adapter is straight, so the hose end and line run straight out of the port.
Are both safe with E85 and methanol?
The Radium adapter states an FKM O-ring rated for gasoline, E85, methanol and oil. The Aeromotive listing only says an O-ring is included, so confirm the material if you run methanol.
Is the Aeromotive fitting legal on a street car?
Its listing says it is not legal for sale or use on emission-controlled vehicles except as a direct replacement matching OEM specs. Check your local rules before fitting it to a fuel system on a registered car.
Do either of these swivel?
No. Both are fixed adapters without a swivel, so you clock the hose end rather than the fitting.
