Fragola -6AN x 9/16-18 (6) Radius Fitting O-Ring - Black

When you're setting up custom fuel or oil lines for your build, getting a solid, leak-free connection is key. This Fragola O-ring fitting is designed to help you achieve just that. It's a simple but important piece for ensuring your hard work doesn't spring a leak under pressure.

This fitting uses a -6AN size on one end and a 9/16-18 O-ring boss on the other, which is a common size for many factory fuel rails or power steering systems. The O-ring design creates a seal that's much more reliable than traditional flare fittings, especially when dealing with higher pressures or vibrations. It's made from aluminum and finished in black for a clean look in your engine bay.
