Radium 8AN ORB To 6AN ORB Swivel Union Fitting | Universal (20-0686)

An 8AN ORB port and a 6AN ORB port can talk directly; this swivel union is the conversation.

The Radium Engineering 8AN ORB to 6AN ORB Swivel Union Fitting joins ORB-ported components across the size step: the 8AN ORB (3/4"-16) end threads into one component, the 6AN ORB (9/16"-18) end into the other, both sealing on O-rings, with the swivel action letting the joint clock and align during assembly instead of fighting thread timing. Direct component-to-component connections, no hose required.

What You'll Feel

• Rails, regulators, filters, and dampers joined directly across the 8AN-to-6AN step
• Assembly alignment solved by the swivel, with no thread-timing puzzles
• Two O-ring seals doing the work, serviceable for the life of the system

Features

• 8AN ORB (3/4"-16) to 6AN ORB (9/16"-18) union with swivel action
• O-ring sealed on both ends; machined anodized aluminum
• All fuel types including E85

The Details

Direct-mount architecture is Radium's signature, with regulators and dampers threading straight into rail ports, and this union extends the idea across mismatched port sizes: a 6AN ORB accessory landing on an 8AN ORB rail port, or a filter and mount pairing whose ports disagree by one size. Both O-rings get lubricated before installation, both ends thread snug against their bosses, and the swivel handles final orientation. As with every ORB joint, no sealant anywhere, and the O-rings are the service item, with Radium's multi-packs keeping spares on the shelf. Sold individually.
