12AN Female to 16AN Male Expander Black

The REDHORSE PERFORMANCE 12AN Female to 16AN Male Expander Black is a precision hydraulic adapter fitting engineered for high-performance fuel, oil, and coolant systems where size transitions are necessary. This expander fitting is designed for users who demand reliable stepped connections in racing engines, custom fuel systems, and professional-grade hydraulic applications. The ability to safely transition between different AN line sizes while maintaining system integrity makes this adapter essential for builders and technicians working with complex plumbing configurations.

Constructed from lightweight yet durable aluminum with black anodized finish, this adapter resists corrosion and oxidation while delivering dependable performance in demanding environments. The 12 AN female inlet accepts standard 12 AN hose or fittings, while the 16 AN male outlet allows connection to larger-diameter components or distribution blocks. Black anodizing provides both aesthetic appeal and functional protection against harsh fuel vapors and fluid exposure. The 952 Series designation indicates REDHORSE's proven design lineage, built to withstand high flow rates and pressure cycles without leakage or structural compromise.

Professional engine builders, drag racing teams, and custom automotive enthusiasts rely on this expander to optimize fuel distribution and system routing. Installation requires standard AN wrench sizes and hand-tight-plus-quarter-turn torque methodology to ensure proper seal without over-tightening. The compact 3.825-inch length and lightweight 0.205-pound design minimize space constraints in tight engine bays while reducing overall system weight. This fitting integrates seamlessly into existing AN-compatible systems and works with all standard -12 and -16 hose, tubing, and component assemblies.
