Radium 8AN ORB Female to 6AN ORB Male Adaptor Fitting

Radium 8AN ORB Female to 6AN ORB Male Adaptor Fitting

This precision-machined adapter fitting converts an 8AN ORB (O-Ring Boss) female port to a 6AN ORB male connection, allowing you to step down between ORB port sizes in a fuel, oil, or coolant system without the need for additional fittings or hose sections.

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. Compatible with all fuel types including E85, ethanol, and methanol.
