10AN Two Piece Flare Cap Nut Clear

The 10AN Two Piece Flare Cap Nut Clear from REDHORSE PERFORMANCE is a precision hydraulic fitting component engineered for high-pressure fluid systems in performance automotive, aircraft, and industrial applications. This cap nut serves as a critical termination point in AN (Army-Navy) standardized plumbing systems, sealing and protecting the end of flare fittings against contamination and fluid loss. Professionals and enthusiasts who demand reliable, leak-free connections in demanding environments choose this component for its proven durability and exact dimensional tolerances.

Manufactured from aluminum and finished in clear anodize, the 10AN Two Piece Flare Cap Nut Clear combines lightweight construction with superior corrosion resistance. The two-piece design allows for easier assembly and disassembly compared to single-piece alternatives, reducing installation time and stress on connected components. Clear anodizing preserves the natural aluminum appearance while providing a protective oxide layer that resists oxidation and extends service life in harsh conditions. The 10 AN sizing ensures compatibility with standard 10 AN male flare fitting threads, delivering a dependable metal-to-metal seal that withstands vibration and thermal cycling typical in motorsports and aerospace applications.

This fitting is ideal for fuel systems, coolant lines, brake systems, and custom hydraulic manifolds where AN-standard connections are required. Engine builders, fuel system integrators, and performance shops rely on REDHORSE PERFORMANCE components to maintain system integrity under extreme pressure and temperature fluctuations. The lightweight aluminum construction makes it particularly valuable in weight-sensitive applications such as race cars and aircraft. Installation is straightforward—simply thread onto the male flare fitting by hand until snug, then torque to specification using standard wrenches. Each unit ships individually, allowing technicians to purchase only the quantity needed for their specific project requirements.
