Straight Adapter Fitting #6 x 1/2 MPT

The Straight Adapter Fitting #6 x 1/2 MPT from FRAGOLA is an essential component for any serious fuel system, hydraulic line, or fluid transfer application where reliable flow and leak-free connections are non-negotiable. Whether you're building a high-performance fuel system for a race engine, upgrading your vehicle's brake lines, or installing aftermarket cooling solutions, this adapter provides the secure, professional-grade connection that prevents costly fluid loss and system failures. Mechanics and fabricators trust FRAGOLA fittings for their precision engineering and durability under demanding conditions.

This straight adapter fitting uses a size #6 connection (which accommodates -6 AN hose or equivalent line) on one end and a 1/2 inch male pipe thread (MPT) on the opposite end, making it ideal for transitioning between hose-based systems and rigid piping infrastructure. The straight design eliminates flow disruption and turbulence, ensuring consistent pressure and volume throughout your system—critical when managing fuel delivery, coolant circulation, or hydraulic applications. FRAGOLA's precision manufacturing tolerances and quality materials resist vibration loosening and thermal cycling, delivering the reliability that high-performance applications demand.

This adapter is ideal for engine builders, fuel system designers, and restoration specialists who require versatile connection options between different line standards. Common applications include fuel system upgrades on carbureted and fuel-injected vehicles, coolant bypass configurations, and hydraulic clutch or brake installations. The compact design—measuring just over 6 inches in overall length and weighing a mere 0.05 pounds—integrates seamlessly into tight engine bays and custom fabrication layouts without adding bulk or weight.
