12AN Flare Cap Nut 2 Piece Blue

The 12AN Flare Cap Nut 2 Piece Blue from REDHORSE PERFORMANCE is a precision hydraulic fitting component engineered for high-pressure fluid systems in racing, automotive, and industrial applications. This two-piece design serves as a secure termination point for AN (Army-Navy) braided hose assemblies, preventing fluid loss and maintaining system integrity under demanding operating conditions. Professionals and enthusiasts rely on these fittings to ensure leak-free connections in fuel systems, coolant lines, and power steering circuits where vibration and pressure cycles demand reliable, repeatable performance.

Constructed from aluminum with blue anodized finish, the 12AN cap nut combines lightweight construction with corrosion resistance and visual identification. The flare design creates a 37-degree conical seating surface that mates precisely with corresponding fittings, distributing clamping force evenly across the joint to prevent galling and ensure a hermetic seal. The two-piece configuration allows for straightforward assembly and disassembly without specialized tools, while the anodized surface protects against oxidation and provides aesthetic distinction in custom hydraulic systems. Each fitting is individually packaged and ready for immediate installation.

This 12AN flare cap nut is essential for fabricators building custom hose lines, restoration specialists maintaining vintage performance vehicles, and engine builders assembling fuel and coolant circuits where code compliance and durability matter. Installation requires mating with 12AN hose ends and compatible manifold or component ports; the straightforward design eliminates guesswork and reduces assembly time. Weighing just 0.12 lbs and compact in footprint, it integrates seamlessly into tight engine bays and chassis layouts. Compatible with all standard 12AN braided hose assemblies and fittings, this REDHORSE PERFORMANCE cap nut is an economical choice for single-fitting replacements or complete system builds.
