-12an Port to 1.500in Hose Fitting

The -12AN Port to 1.500in Hose Fitting is a precision adapter designed for high-flow cooling and fuel system applications where reliable connections between different port standards are essential. Built by MEZIERE, a trusted name in performance cooling systems, this straight adapter allows technicians and enthusiasts to integrate 12 AN male ports with 1.5-inch hose barb connections seamlessly. Whether you're upgrading a custom cooling loop, plumbing a fuel system on a race engine, or retrofitting a performance vehicle, this fitting eliminates compatibility issues and ensures leak-free operation under demanding conditions.

Machined from aluminum and polished to a professional finish, the -12AN Port to 1.500in Hose Fitting delivers both durability and aesthetic appeal in engine bay applications. The straight-port design minimizes turbulence and pressure drop, critical factors in maintaining system efficiency during sustained high-RPM operation. Its aluminum construction provides excellent thermal conductivity while remaining lightweight, and the polished surface resists corrosion while simplifying inspection and maintenance. The hose barb end accommodates standard 1.5-inch diameter hose, secured with industry-standard hose clamps for a dependable, vibration-resistant seal that won't weep or fail under thermal cycling.

This adapter is ideal for custom cooling system builds, fuel system conversions, and engine bay plumbing projects where AN port standards don't align with existing hose infrastructure. It's equally suited for street rod builders, drag racing setups, and street-performance vehicles requiring compact, reliable port-to-hose transitions. Installation is straightforward: thread the 12 AN male end into your engine block, radiator, or fuel rail fitting, then slide the 1.5-inch hose over the barb and secure with two hose clamps. Verify all connections are tight and leak-free before pressurizing the system, and ensure hose routing clears hot exhaust components and moving engine parts.
