Our take on the Radium Engineering Universal 10AN Orb Plug

The Radium Engineering 10AN ORB Plug is a billet aluminum plug that seals any 7/16"-20 O-ring boss port, the same thread used on -4AN ORB fittings. It uses an FKM (Viton) O-ring, so it holds up to oil, fuel and most automotive fluids. It is a small, single-purpose part for capping unused ports on fuel systems, oil systems and catch cans. Compared with generic hardware-store plugs, it is machined for a precise fit and comes with the correct O-ring already installed.

About the Radium Engineering Universal 10AN Orb Plug

This is an ORB plug from Radium Engineering, made from anodized billet aluminum. It fits any application that uses a 7/16"-20 O-ring port. That is the same thread pitch used in -4AN, and ORB stands for O-Ring Boss.

The plug has an FKM (Viton) O-ring, which suits all oil and fuel types.

It is not application specific. Check compatibility before buying, as some modification may be needed for proper installation.

Questions and answers

What port does this plug fit?
It fits any port threaded 7/16"-20 with an O-ring boss seat, the same thread as -4AN ORB. It will not fit NPT, metric or other AN sizes.
What fluids can it seal?
The FKM (Viton) O-ring is rated for oil and fuel types, including gasoline and ethanol blends. It is not intended for brake fluid or coolant.
Is it the same as a -10AN plug?
No. The 10AN in the name refers to the plug's hex size, while the thread is 7/16"-20, which is -4AN ORB. Check your port thread before ordering.
Does it come with the O-ring?
Yes, the plug ships with its FKM O-ring installed. Inspect the O-ring before fitting and replace it if it is nicked or flattened.
How tight should I tighten it?
Snug it against the O-ring seat; the O-ring does the sealing, so it does not need heavy torque. Over-tightening can damage the O-ring or the port.
Can I reuse it?
Yes, if the O-ring is in good shape. Replace the O-ring if it is compressed, cracked or has been exposed to harsh solvents.
