3AN Male to Male Flare Union Clear

The 3AN Male to Male Flare Union Clear from REDHORSE PERFORMANCE is a precision-engineered hydraulic and fuel system adapter designed for high-performance applications where reliable, leak-free connections are non-negotiable. This straight-configuration fitting serves as a critical junction point in custom fluid transfer systems, plumbing networks, and motorsport fuel or brake line assemblies where two male AN fittings must be joined securely. Built for professionals and enthusiasts who demand durability and consistency, this adapter eliminates guesswork from system assembly and ensures compatibility across standardized AN (Army-Navy) threaded components.

Manufactured from aluminum and finished with clear anodizing, the 3AN Male to Male Flare Union delivers a balance of lightweight strength and corrosion resistance essential in modern performance vehicles. The flare union design uses JIC (Joint Industry Council) 37-degree flare connections at both ends, creating a mechanically robust seal that withstands pressure cycles without relying solely on thread engagement. Clear anodizing preserves the natural aluminum appearance while adding a protective oxide layer that resists oxidation and maintains visibility for system inspection. The compact 2.835 x 1.095 x 4.423 inch profile and minimal 0.083 lbs weight make integration straightforward in space-constrained engine bays and custom fabrication projects.

This fitting is ideal for builders of custom fuel systems, EFI conversions, high-flow cooling circuits, and race-spec brake line modifications where OEM plumbing cannot accommodate dual male connections. Installation requires no special tools beyond a standard wrench or AN wrench set; proper torque and thread sealant (PTFE tape or anaerobic compound) ensure lasting performance. The 815 Series designation confirms compatibility with other REDHORSE 3AN components, enabling seamless system expansion and replacement without hunting for adapter variants.
