Fuelab Expander Port Fitting -12AN ORB to -16AN 37 Flare

Fuelab is known for making fuel system components that work well in demanding setups. This fitting is a good example, letting you connect a -12AN O-ring boss port to a -16AN 37-degree flare hose end. It's a common need when you're building or modifying a fuel system and need to adapt between different fitting sizes or types.

This fitting is made from aluminum, which keeps the weight down. The -12AN ORB side threads into a port that uses an O-ring seal, while the -16AN side is a standard 37-degree flare designed to seal with a matching flare on a hose fitting. It's a straightforward piece that does exactly what it's supposed to do: bridge the gap between two different AN sizes.
