Description
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.
Suits: Universal — any application requiring an 8AN ORB female to 6AN ORB male step-down adapter
Specifications:
- Female port: 8AN ORB (3/4-16 thread)
- Male port: 6AN ORB (9/16-18 thread)
