The DeatschWerks 8AN female flare nut is a replacement nut for securing 8AN hardline tubing assemblies. It fastens male flare fittings to tubing or adapters in larger AN-style fluid systems, helping create a proper mechanical seal for fuel or oil lines when building or repairing custom hard-line connections that use 8AN hardware.
