#6 x #10 Male Reducer Black

The FRAGOLA #6 x #10 Male Reducer Black is a hydraulic hose adapter designed for fuel systems, brake lines, and custom fluid transfer applications in high-performance vehicles and engine builds. This reducer is essential when adapting from smaller bore #6 fittings to larger #10 ports, which is a common requirement for aftermarket fuel rails, brake calipers, or transmission cooler lines.

Constructed from black anodized aluminum, this adapter features precision-engineered AN-spec threading that ensures reliability under pressure and thermal cycling typical in modified engines. The #6 SAE inlet is compatible with standard -6 hose assemblies, while the #10 SAE outlet threads directly into factory or aftermarket component ports, preventing leakage and flow restriction.

This adapter is particularly beneficial for carburetor conversions, EFI retrofits, and turbo cooling system upgrades, providing seamless integration into tight manifold spaces. FRAGOLA's reputation for leak-free AN fittings ensures that this adapter performs reliably across fuel, oil, coolant, and transmission fluid circuits.
