AN to O-Ring -8 x 1 1/16-12 (-12)

The AN to O-Ring -8 x 1 1/16-12 (-12) adapter from Triple X Race Components is an essential fluid transfer coupling for high-performance automotive and racing applications. This adapter bridges AN (Army-Navy) hose fittings to O-ring face seal (ORFS) ports, enabling reliable connections in fuel systems, coolant lines, and hydraulic circuits where precision engineering is non-negotiable. Whether you're building a custom fuel injection setup, upgrading brake lines on a track car, or plumbing a modified cooling system, this -8 size adapter ensures leak-free performance under extreme pressure and temperature fluctuations.

The -8 designation refers to a 1/2-inch nominal hose ID, while the 1 1/16-12 thread specification defines the O-ring port interface—a standard size across domestic and import performance platforms. Triple X Race Components manufactures this adapter from forged aluminum or ductile iron with precision machining to aerospace tolerances, ensuring the sealing surfaces mate perfectly with both AN flare fittings and ORFS ports. The O-ring design eliminates reliance on flare-based seals alone, providing a metal-to-metal face contact that resists vibration, thermal cycling, and pressure spikes common in forced-induction and nitrous oxide systems.

Fabricators and engine builders favor this adapter for fuel rails, transmission coolers, turbo feed/return lines, and custom manifold ports where space or thread availability limits direct AN connections. Its compact 1.5-inch profile fits tight engine bays while maintaining full flow path integrity. Always confirm your specific ORFS port diameter and AN hose barb size before installation; this -8 unit is engineered for 1/2-inch hose systems running up to 250+ psi. Pair it with quality stainless steel hose, proper fittings, and periodic inspection for maximum reliability in street or competition duty.
