As seen above, all female -AN ports can accept 37 degree flare male fittings and/or ORB (O-ring boss) male fittings. As depicted below, the flow direction is laser etched on the side of the part.

The check valve is compatible in multiple applications including gasoline, ethanol, methanol, diesel, water, coolant, oil, etc.
