3AN Flare Plug 2/pkg Blue

The 3AN Flare Plug 2/pkg Blue from REDHORSE PERFORMANCE is a professional-grade hydraulic fitting designed for high-pressure fluid systems in racing, automotive, and industrial applications. This pair of aluminum plugs seals AN ports with precision, preventing fluid loss and contamination in critical fuel, oil, and coolant lines. Technicians and engine builders rely on these fittings to maintain system integrity under demanding conditions where reliability is non-negotiable.

Each plug features a 3 AN port size with a hex head design that allows secure installation and removal using standard wrenches, eliminating the need for specialized tools. The blue anodized aluminum construction provides both corrosion resistance and lightweight performance while meeting stringent aerospace and automotive standards. The flare-plug design creates a positive mechanical seal that accommodates vibration and thermal cycling without degradation, ensuring long-term dependability in extreme environments where conventional fittings may fail.

This two-pack configuration is ideal for builders completing fuel system upgrades, cooling system modifications, or hydraulic line routing on custom engines and performance vehicles. The 3AN size integrates seamlessly with REDHORSE 806 Series manifolds, adapters, and hose fittings, simplifying system assembly and ensuring leak-free connections. Installation is straightforward—apply thread sealant to the hex head fitting and torque securely into any standard 3 AN female port for immediate system closure.
