8AN to 6AN O-Ring Port Adapter Blue Male Male

The REDHORSE PERFORMANCE 8AN to 6AN O-Ring Port Adapter Blue Male Male is a precision straight fitting designed to connect two different AN port sizes in high-pressure hydraulic and fuel systems. This 920 Series adapter serves as a critical junction point in performance fuel injection systems, transmission coolers, and custom fuel distribution networks where AN -8 line connections must interface with AN -6 components without compromising system integrity.

Manufactured from aerospace-grade aluminum with a blue anodized finish, this male-to-male port adapter features integrated O-ring sealing technology that eliminates the need for thread sealant tape or liquid sealants. The anodized coating provides corrosion resistance in harsh underhood environments while maintaining the adapter's lightweight profile at just 0.07 lbs. The straight-port design minimizes pressure drop and turbulence, critical in systems where fuel delivery speed and flow efficiency directly impact engine performance. Each adapter is produced to REDHORSE's precision standards, ensuring tolerances that prevent leaks and system degradation over time.

This adapter is essential for builders and technicians customizing fuel systems on high-performance vehicles, race engines, and specialty automotive applications. It solves a common plumbing challenge: stepping down from a larger AN -8 feed line to a smaller AN -6 outlet or component without introducing leaks or vibration-induced failures. The O-ring port design is superior to JIC or NPT alternatives because it eliminates thread stripping and provides a metal-to-metal sealed interface that holds pressure under dynamic load cycles.

AN fittings are the industry standard in motorsports, aerospace, and custom automotive fabrication because they offer superior reliability under vibration and pressure cycling compared to conventional NPT threads. REDHORSE Performance adapters maintain the integrity of this system by holding OEM tolerances and material specifications, making this fitting suitable for street vehicles, track applications, and systems operating at sustained high pressures.
