1/2in Hose to 3/8in NPT Male Straight Blue

The 1/2in Hose to 3/8in NPT Male Straight Blue adapter from REDHORSE PERFORMANCE is engineered for professionals and enthusiasts who demand reliable fluid transfer connections in high-performance applications. This straight fitting adapter bridges 1/2-inch hose barb connections to 3/8-inch NPT male threads, making it essential for fuel systems, coolant lines, and pressurized fluid circuits where leak-free performance is non-negotiable. Whether you're building a custom fuel system, modifying hydraulic lines, or assembling pneumatic equipment, this adapter provides the secure, durable interface your system requires.

Constructed from aluminum and finished in blue anodize, this 840 Series fitting combines lightweight strength with corrosion resistance—critical properties in demanding environments where moisture and thermal cycling can compromise inferior materials. The barbed hose end accepts 1/2-inch ID tubing with positive mechanical grip, while the 3/8-inch NPT male thread end accommodates standard pipe fittings, blocks, and manifold ports with precision engagement. Blue anodizing protects against oxidation and provides visual identification within color-coded system layouts, while aluminum construction keeps weight minimal without sacrificing durability or pressure rating.

This adapter is ideal for racing fuel systems, performance cooling upgrades, custom brake line installations, and industrial fluid power assemblies where mixing hose and NPT connections is unavoidable. Its compact 2.8 x 1.1 x 3.75-inch profile fits tight engine bays and manifold blocks, and the straight configuration eliminates turbulence and pressure drops common to angled fittings. For reliable connections that withstand vibration, temperature fluctuations, and sustained pressure, the 1/2in Hose to 3/8in NPT Male Straight Blue adapter is the OEM-quality choice trusted by system builders and performance shops.
