AN to Metric Straight Adapter -6AN to M12x1.25

The AN to Metric Straight Adapter -6AN to M12x1.25 is a precision hose fitting designed to connect SAE AN (Army-Navy) threaded ports to metric ISO 4401 (CETOP) manifold connections. This adapter bridges two industry-standard hydraulic and pneumatic systems commonly found in high-performance automotive, aerospace, and industrial applications where legacy and modern equipment must interface seamlessly.

Constructed from aluminum and finished in black anodized coating, this straight adapter provides corrosion resistance while maintaining a lightweight profile suitable for tight engine compartments and mobile installations. The -6AN male thread (0.75-16 UNF) mates directly to metric M12×1.25 male ports without additional components. The aluminum construction meets industry standards for fluid system applications while the anodized finish protects against oxidation in both dry and moderately corrosive environments. Compact dimensions (3.55 × 1 × 4.1 inches) and minimal weight (0.03 lbs) make this fitting ideal for space-constrained installations where bulk and added system weight must be minimized.

This adapter is essential for technicians and engineers integrating American-standard hydraulic systems into metric-based platforms—including performance fuel systems, turbo boost controllers, air suspension networks, and custom fabrication projects. The straight configuration eliminates stress concentration points present in 90-degree adapters, reducing potential leak paths in high-vibration environments like rally vehicles, marine engines, and agricultural equipment. Each adapter ships as an individual unit, allowing precise system configuration without overbuying.

AN-to-metric conversion fittings remain a critical bridge component wherever American hydraulic heritage equipment operates alongside European and Asian metric-standard infrastructure. This -6AN to M12×1.25 straight adapter delivers that connection with proven aluminum durability and anodized corrosion protection, backed by verified dimensional accuracy for reliable, leak-free operation in demanding fluid systems.
