Fragola -4AN Aluminum Flare Plug - Black

Fragola's 480604-BL is a -4AN aluminum flare plug that caps off any unused -4AN port or line end. It threads in with a standard 7/16-20 male thread and a 37-degree JIC flare, creating a positive seal without any additional hardware or sealant on the flare side.

Made from aerospace-quality aluminum and machined to mil-spec tolerances, this plug matches the build standard of Fragola's full line of AN fittings. The black anodized finish resists corrosion and keeps your plumbing looking uniform if the rest of your AN fittings are also in black. At under two dollars, it is an easy add-on when you are building a fuel system, oil system, or coolant loop and need to blank off a port you are not using yet.
