The AN to NPT 90 Degree -12 x 1/2in adapter from ALLSTAR PERFORMANCE is a precision hydraulic and fuel system fitting engineered for high-pressure applications requiring AN (Army-Navy) to NPT (National Pipe Thread) conversion. This 90-degree elbow connector bridges two of the most common industrial threading standards, making it essential for engine builders, race teams, and fluid system integrators who need reliable transitions between different port types. The right-angle design saves space in tight engine bays and manifold assemblies where inline fittings cannot accommodate physical constraints.
Manufactured from aluminum and finished in black anodize, this fitting combines lightweight construction with corrosion resistance and durability in demanding environments. The -12 AN male port (3/4-inch diameter) connects seamlessly to 1/2-inch NPT male threads, providing a secure, leak-free seal under pressure when paired with appropriate thread sealant or PTFE tape. Black anodized aluminum offers superior strength-to-weight ratios compared to brass alternatives, while the anodize coating protects against oxidation and provides a professional appearance on visible installations. Each fitting is manufactured to strict tolerances to ensure proper seating and minimize vibration-induced loosening.
Professional automotive builders, fuel system manufacturers, and hydraulic technicians rely on this adapter for carbureted fuel systems, turbo oil return lines, and coolant bypass circuits where size and angle constraints demand compact solutions. Installation requires standard wrench and plier techniques; applying thread sealant to NPT ports ensures leak-proof performance under vibration. This single-unit fitting integrates into custom plumbing assemblies, prototype builds, and restoration projects where precision fittings and authentic AN-to-NPT conversions are non-negotiable for safety and reliability.
