Fragola -6AN Port Plug 9/16-18 w/ 1/8 FPT Port - Black

This is a Fragola -6AN port plug, designed to seal off an unused -6AN fitting. It features a 9/16-18 thread size, which is standard for -6AN fittings, and also includes a 1/8" female pipe thread (FPT) port. This allows you to plug a port while still having a small threaded opening available, perhaps for a sensor or a small gauge, without needing a separate adapter.

The plug is made from aluminum and finished in black, giving it a clean look that blends well with most engine bays. It's a straightforward component that's useful when you're fabricating or modifying fuel lines, oil lines, or other fluid transfer systems on your vehicle. Having a few of these on hand can save you a trip to the parts store when you realize you've got an extra port you need to close off.
