Radium AN ORB to Male AN Flare Fitting

Radium AN ORB to Male AN Flare Fitting

These precision-machined adapter fittings convert AN ORB (O-Ring Boss) ports to male AN flare connections, providing versatile plumbing options for fuel rails, surge tanks, fuel pressure regulators, and other high-performance fuel system components. Available in 8 size combinations across 6AN, 8AN, and 10AN ORB and flare sizes.

AN ORB fittings use positive O-ring sealing rather than tapered threads — no PTFE paste or thread sealant required. Lubricate the O-ring with engine oil before installation. ORB ports are an industry standard found on most Radium Engineering products and a wide range of aftermarket fuel system components.

Suits: Universal — fuel rails, surge tanks, fuel pressure regulators, and all AN ORB ported components
