#16 Female x #12 Male Swivel Reducer Black

The FRAGOLA #16 Female x #12 Male Swivel Reducer Black is a precision hydraulic hose fitting designed for custom fuel, coolant, and brake line applications in high-performance automotive builds. This essential adapter is ideal for systems requiring stepped-down line transitions, such as installing a custom fuel rail on a carbureted engine swap or adapting modern fuel injection to a vintage chassis.

Manufactured to SAE specifications, this swivel reducer features a full 360-degree swivel design on the female end, allowing for flexible positioning without rotational stress on the hose barbs or male ports. The #16 female port accepts standard -16 AN hose (1-inch inner diameter), while the #12 male outlet threads into -12 AN receiving ports with a 0.75-inch inner diameter, ensuring a smooth and reliable transition between dissimilar line sizes. The black anodized aluminum construction resists corrosion and maintains structural integrity under pressure and heat cycling.

This reducer is particularly beneficial for mechanics working in tight installation areas, as its compact 4.25-inch length allows for efficient routing of fluid pathways without excessive hose bends that could reduce flow or create failure points. Whether you're routing coolant lines through a tight engine bay during a full rebuild or optimizing fuel systems, this reducer provides the professional flexibility needed for high-performance applications.
