12AN Male to 6AN Male Reducer Black

The 12AN Male to 6AN Male Reducer Black from Redhorse Performance is a vital hydraulic line adapter designed for high-performance fuel, oil, and coolant systems. This reducer is essential for integrating step-down fittings, bridging the gap between larger 12AN ports and smaller 6AN lines. It is particularly useful for custom fuel injection setups, turbo cooling circuits, and precision engine bay plumbing.

Manufactured from black anodized aluminum, this reducer features precision-engineered male threads on both ends (12AN inlet, 6AN outlet) that securely seat without the need for thread sealant tape when used with O-ring equipped fittings. The compact design, with an overall length of 2.85 inches, is lightweight and ideal for tight engine compartments where efficient line routing is crucial. The anodized finish not only provides corrosion resistance but also enhances the aesthetic appeal.

This reducer is perfect for mechanics and engine builders looking to upgrade fuel delivery systems or install aftermarket turbocharger coolers. By ensuring a properly matched reducer, users can prevent leaks and maintain system integrity, avoiding the need for improvised adapter stacks that may compromise reliability. Its robust construction is critical for maintaining consistent fuel pressure in both carbureted and fuel-injected engines.
