Radium Engineering 8AN ORB Plug vs Radium 6AN ORB to 8AN Male Fitting

These are not competing versions of the same part. The Radium 8AN ORB Plug (14-0150) is a blanking plug that seals an unused 3/4"-16 ORB port. The Radium 14-0245 is an adapter that converts a 6AN ORB port to an 8AN male flare. Buy the plug to close a spare -8 ORB port, and buy the adapter to step a -6 ORB port up to an -8 line. Both are machined aluminum Radium pieces with O-ring sealing on the ORB side, and owners rate Radium's AN hardware for clean threads and leak-free sealing.

  • Choose the Radium 8AN ORB Plug if you need to seal an unused 3/4"-16 ORB port on a fuel system, oil system or catch can.
  • Choose the Radium 6AN ORB to 8AN Male adapter if you have a -6 ORB port and need to run an -8AN hose or fitting from it.

Questions and answers

Which one do I need for a spare port?
The 8AN ORB Plug. It seals an unused 3/4"-16 ORB port. The 14-0245 adapter is for connecting a line, not closing one.
Can I use the plug to adapt a -6 ORB port to -8AN?
No. The plug has a 3/4"-16 ORB thread and blocks flow. Use the 14-0245 adapter to go from 6AN ORB to 8AN male.
Are these the same thread?
No. The plug is -8AN ORB (3/4"-16). The adapter starts at -6AN ORB and ends in an 8AN male flare.
Which lasts longer?
Both are machined aluminum Radium fittings with O-ring sealing. Life depends on install torque and fluid, not on which one you pick.
Is the adapter worth stepping up to over a two-piece setup?
A single Radium adapter removes one joint and one potential leak point compared with stacking fittings. That is the main reason to choose it.
