About the Radium Engineering 6AN ORB to .313" SAE Male Fitting
Radium 6AN ORB to .313" SAE Male Fitting
Application: Universal – 6AN ORB (9/16"-18) O-ring ports
Part Type: 6AN ORB to .313in (5/16in) SAE quick connect male adapter fitting
Part Number: 14-0646
The Radium 14-0646 is part of Radium's 6AN ORB fitting range, listed under its 6AN ORB to SAE quick connect connections. It threads into a 6AN ORB port and provides an SAE quick connect male end.
Radium's anodised billet aluminium adapter fittings can be used in any application with a 9/16"-18 O-ring port, the same thread pitch used on 6AN ORB (O-ring boss) fittings. They use FKM O-rings that are compatible with all oil and fuel types. SAE quick connect fittings push on and secure to most modern USA, European and Japanese fuel injection systems, so OEM quick connect fuel lines can be adapted to aftermarket plumbing.
Key Features
6AN ORB Thread: 9/16"-18 O-ring boss thread
SAE Quick Connect: Male SAE quick connect connection for OEM-style quick connect fuel lines
Billet Aluminium: Anodised billet aluminium construction
FKM O-Rings: Compatible with all oil and fuel types
Important Notes
• Lubricate the O-rings with engine oil, O-ring lube or petroleum jelly before installation
• To confirm the SAE quick connect size you need, measure the outside diameter of the male fitting: 0.3125in = 5/16in, 0.375in = 3/8in, 0.500in = 1/2in, 0.625in = 5/8in
