8an Male to 8an Female w/ 1/8npt Hex

The 8AN Male to 8AN Female with 1/8 NPT Hex fitting from REDHORSE PERFORMANCE is a critical adapter for custom automotive hydraulic and fluid line systems. Whether you're building a high-performance cooling circuit, custom fuel system, or precision brake line configuration, this fitting bridges two different AN (Army-Navy) connection sizes with integrated NPT capability. Built for serious enthusiasts and fabricators who demand reliable, leak-free connections in demanding engine bay environments, this adapter eliminates the need for multiple fittings and reduces assembly complexity in compact installations.

This adapter features a male 8AN outlet and female 8AN inlet, allowing you to transition between different hose terminations or consolidate multiple lines into a single junction point. The integrated 1/8 NPT hex port provides a secondary connection point for gauges, sensors, or auxiliary lines—essential when space is tight and you need functional versatility without adding bulky T-fittings. REDHORSE PERFORMANCE fittings are manufactured to strict aerospace tolerances, ensuring precise thread engagement, minimal vibration-induced loosening, and dependable performance across temperature and pressure cycles common in modified vehicle applications.

This fitting excels in custom cooling systems, fuel distribution networks, and hydraulic brake upgrades on track-focused builds, drift cars, and high-displacement engines where OEM hose routing won't accommodate performance modifications. Its compact form factor (3.8 × 1.05 × 3.95 inches) makes it ideal for engine bay applications where real estate is limited. Mechanics and fabricators favor REDHORSE adapters for their durability, resistance to corrosion, and compatibility with braided stainless steel hose, aluminum hard lines, and professional-grade fluid systems.
