Fragola -20AN Aluminum Flare Plug

This Fragola aluminum flare plug uses a -20AN size fitting, which is a common size for high-flow fuel or oil lines. It's made from aluminum, making it lightweight and resistant to corrosion in most engine bay environments. You'd typically use a plug like this when you're cleaning up a custom plumbing setup, like on a race car or a heavily modified street machine, and need to seal off a port that's no longer in use. It's a simple part, but getting the right size and a good seal is important to prevent leaks.

The aluminum construction means it won't add much weight to your plumbing, and it's easy to work with. Just thread it into the unused fitting until it's snug. Since it's a flare plug, it seals against the flare of the fitting itself, not the threads, which helps create a reliable seal without needing any thread sealant. It's a straightforward way to cap off a line and keep your system clean and leak-free.
