Fitting -10an Positive Seal

The Fitting -10AN Positive Seal from MOROSO is a precision hydraulic and fuel line connector engineered for high-performance automotive systems where reliability and leak prevention are non-negotiable. Designed for serious enthusiasts and professional builders, this -10 AN male fitting delivers the secure, vibration-resistant connection demanded in racing engines, custom fuel systems, and pressurized hydraulic applications. The positive seal design eliminates the need for secondary O-ring backup, reducing assembly complexity while ensuring dependable performance under demanding conditions.

Constructed from aerospace-grade aluminum and finished in durable black anodizing, this fitting resists corrosion and maintains structural integrity across temperature extremes and chemical exposure. The positive seal mechanism creates a metal-to-metal contact surface that locks onto hose ends without relying on elastomer seals alone, making it ideal for applications subject to thermal cycling or aggressive fluid exposure. The -10 AN sizing accommodates standard braided hose and tubing in high-flow fuel delivery, transmission cooling, and brake bias systems commonly found in race cars, hot rods, and modified performance vehicles.

Installation is straightforward for fabricators and technicians familiar with AN system standards—the vented design prevents vacuum lock during draining or system priming. This fitting pairs seamlessly with -10 AN braided hose, aluminum or steel tubing, and compatible manifolds in fuel systems rated for 100+ PSI and hydraulic circuits demanding zero-leak performance. Whether upgrading a vintage restomod fuel system, assembling a competition engine bay, or fabricating custom brake lines, the MOROSO Fitting -10AN Positive Seal delivers the precision and durability that separates amateur builds from professional-grade installations.
