Our take on the Radium Engineering 6 AN ORB Fittings Plug

This is a -6 AN O-ring boss plug machined from billet aluminum and anodized. It seals a 9/16"-18 O-ring port, the same thread used for -6 AN ORB fittings, and comes with an FKM (Viton) O-ring rated for oil and fuel. It suits anyone capping an unused ORB port on a fuel system, oil system or catch can. Against generic hardware-store plugs, it offers a proper O-ring seal and fuel-compatible material rather than a bare threaded plug.

Questions and answers

What port does this plug fit?
A 9/16"-18 O-ring boss port, the same thread as -6 AN ORB. It will not fit NPT, metric or larger ORB ports.
Is it safe with fuel and oil?
Yes. The FKM (Viton) O-ring is specified for all oil and fuel types, which is the main reason to pick it over a plain plug.
What is included?
One anodized billet aluminum plug with its FKM O-ring. It is a single plug, not a multi-pack.
Can I use it to block a port on a catch can or surge tank?
Yes, as long as that port is 9/16"-18 ORB. It is a common way to close unused ports on Radium and similar tanks.
Does it come with a sealing washer?
No. It seals on the O-ring against the port face, so no crush washer is used.
Where is the Radium Engineering 6 AN ORB Fittings Plug cheapest?
At Walmart, for $24.52, as of our latest check.
