Russell Performance -4 AN Flare Union (Blue)

This is a Russell Performance -4 AN Flare Union adapter fitting, finished in a classic blue anodized look. It's made from lightweight 6061-T6 aluminum, which is a solid choice for keeping weight down in your fuel or oil system. This fitting is designed to connect two -4 AN hose ends or hardlines together, creating a secure junction in your custom plumbing.

Russell makes these fittings with precision machining to ensure a positive seal, even when your system is running at its maximum operating pressures. Whether you're setting up a new fuel system, modifying your oil lines, or connecting to a fuel pump or filter, this adapter offers a reliable way to join your AN lines. The blue anodized finish not only looks sharp but also helps protect the aluminum from corrosion.
