10AN to 10AN Flare Union AN/AN

The 10AN to 10AN Flare Union AN/AN from REDHORSE PERFORMANCE is a straight adapter fitting designed for high-pressure hydraulic and fuel line systems that demand precision fluid transfer. This fitting bridges two 10 AN male ports with a secure flare connection, making it essential for custom fuel systems, performance engine builds, and industrial hydraulic applications where reliability and leak-free operation are non-negotiable. Technicians and performance enthusiasts select this adapter when original equipment configurations require point-to-point connection between identical AN port sizes.

Constructed from aluminum and finished with a vibrant blue anodized coating, this fitting offers both corrosion resistance and visual identification in complex fuel and hydraulic layouts. The straight 815 Series design incorporates JIC 37-degree flare sealing geometry, which creates a metal-to-metal cone interface that withstands pressure cycling and thermal expansion without thread degradation. The 10 AN male-to-male configuration uses industry-standard AN sizing, ensuring compatibility across all certified hydraulic components and fuel delivery systems engineered to AN specifications.

This adapter serves drag racers, road course competitors, street performance builders, and industrial fluid power technicians who integrate REDHORSE fittings into custom plumbing runs. Installation requires flared line ends on both sides and hand-tightening followed by wrench torque to specification—no thread sealant is needed due to the flare seal design. The compact 2.8 x 1.4 x 3.75 inch footprint and minimal 0.11 lb weight make it ideal for engine bay layouts where space and weight savings matter, while the blue anodize finish aids system traceability during maintenance and diagnostics.
