Radium 6AN ORB To .313in SAE Male Fitting | Universal (14-0646)

An ORB port on one side, a factory quick connect line on the other, one fitting between.

The Radium Engineering 6AN ORB to 5/16" (0.3125") SAE Male Fitting bridges Radium hardware and OEM plumbing: the 6AN ORB end threads into any female 6AN ORB port sealing on its O-ring, and the 5/16" SAE male end accepts factory-style female quick connect fittings, letting the OEM line click straight onto the aftermarket component.

What You'll Feel

• Factory quick connect lines clicking onto Radium filters, rails, and FSTs directly
• A positive O-ring seal at the port with OEM-style service at the line
• Staged upgrades kept simple, the stock plumbing meeting the new hardware halfway

Features

• 6AN ORB (9/16"-18) male thread with O-ring seal
• 5/16" SAE male quick connect interface for factory female fittings
• Machined anodized aluminum; all fuel types including E85

The Details

The 5/16" SAE standard covers return lines and smaller feed circuits across OEM platforms, and the fitting serves the common staged-build moment where a Radium component arrives before the full AN conversion does: ORB end lubricated and threaded home, factory line clicked onto the SAE end until it locks, retention verified with a gentle pull. Confirm the line measures 5/16" rather than 3/8" before ordering, since the SAE sizes do not interchange. Sold individually.
