8AN Flare Plug 1/pkg Blue

The 8AN Flare Plug 1/pkg Blue by REDHORSE PERFORMANCE is a precision hydraulic fitting designed for high-pressure fuel, oil, and coolant systems in performance and custom vehicles. This compact adapter serves as a critical termination point in modified fuel lines, transmission coolers, and engine cooling circuits where AN (Army-Navy) standardized connections are required. Whether you're building a turbocharged engine bay, installing a custom fuel system, or upgrading to braided stainless steel lines, a reliable flare plug prevents fluid leaks at dead-end ports and maintains system integrity under boost and sustained load.

REDHORSE PERFORMANCE flare plugs feature a 37-degree JIC flare design that seats securely into matching female AN fittings, creating a leak-free metal-to-metal seal without additional sealant tape or compounds. The 8AN size accommodates larger flow requirements typical of fuel rails, intercooler piping, and transmission oil circuits found in modified and race applications. The blue anodized aluminum construction provides corrosion resistance while remaining lightweight, critical for engine bay temperatures and long-term reliability in high-performance environments. Each plug is individually packaged to prevent damage and ensure you receive a perfectly formed flare face ready for immediate installation.

Engine builders, fabricators, and automotive technicians rely on REDHORSE flare plugs to complete custom fuel delivery systems, transmission cooling loops, and engine modifications where port termination is necessary. This single-unit package is ideal for one-off custom work, kit assembly, or stocking your shop for frequent hot rod and motorsport builds. Compatible with all standard AN line fittings and aluminum or steel -8 hose assemblies, the 8AN Flare Plug integrates seamlessly into any performance fuel system, whether naturally aspirated or turbocharged. Installation requires only a properly sized AN wrench—no special tools or torque specs beyond general fastener best practices.
