16AN Male to 12AN Male Reducer Black

The REDHORSE PERFORMANCE 16AN Male to 12AN Male Reducer Black is a precision hydraulic adapter designed for custom fuel, oil, and coolant systems in high-performance vehicles. This fitting serves as a transition component when downsizing from larger 16AN (JIC -16) hose lines to smaller 12AN (-12) connections, making it useful for builders needing flexibility in system plumbing layouts.

Constructed from aluminum with a black anodized finish, this adapter combines durability with corrosion resistance, which is critical for underhood environments exposed to heat cycles, fuel vapors, and moisture. The male-to-male configuration on both ends allows seamless integration into existing hose assemblies with standard AN fittings, while the precision-engineered bore ensures minimal turbulence and optimal flow characteristics for fuel delivery and coolant circulation.

Engine builders, fuel system specialists, and DIY enthusiasts will benefit from this reducer when tackling custom loop plumbing, turbo fuel setups, and complete engine bay renovations. Its design is compatible with industry-standard -16 and -12 JIC hose and fitting systems used across professional racing and street performance applications.
