The FRAGOLA #6 Port Plug 9/16-18 is a precision aluminum fitting designed for high-pressure hydraulic and fuel system applications where reliable port closure is essential. This fitting is ideal for builders and technicians who demand OEM-quality closure components for custom fuel rails, manifold blocks, and modular cooling systems.
Constructed from aluminum and finished with blue anodizing, this #6 AN port plug features an O-ring seal design that eliminates the need for thread sealant tape while maintaining consistent leak-free performance across thermal cycling and vibration exposure. The hex head design facilitates quick installation and removal with standard wrenches, reducing downtime during system assembly or maintenance.
The 9/16-18 thread specification ensures compatibility with standard 6 AN port configurations found in race engine fuel systems, transmission cooler lines, and hydraulic brake circuits. Whether closing unused 6 AN ports on a performance fuel system or replacing worn plugs in an existing hydraulic setup, this FRAGOLA part delivers the precision fit and durability expected from a manufacturer known for aerospace-grade fluid components.
