1/2in NPT ML - 1/4in NPT FM Reducer Black

The 1/2in NPT ML - 1/4in NPT FM Reducer Black from REDHORSE PERFORMANCE is a precision adapter fitting engineered for custom hydraulic and pneumatic systems in performance vehicles and engine builds. This straight reducer bushing solves a critical problem in automotive plumbing: connecting larger diameter ports to smaller diameter components without complex manifold modifications or custom fabrication. Whether you're building a race engine with custom cooling lines, installing auxiliary fuel systems, or integrating aftermarket turbocharger components, this fitting enables seamless port adaptation with reliable sealing and minimal pressure loss.

Manufactured from aluminum and finished in black anodized coating, the 912 Series fitting provides both corrosion resistance and lightweight construction—critical factors in performance engine bays where thermal cycling and fluid exposure demand durability. The 1/2 inch NPT male thread connects to larger system components while the 1/4 inch NPT female outlet accommodates smaller diameter hoses, fittings, or sensors. Black anodizing protects against oxidation and provides a professional appearance in visible installations. Weighing just 0.07 lbs, this compact reducer (measuring 2.8 x 1.15 x 3.8 inches) installs without adding unnecessary mass to your build, a priority in weight-conscious automotive applications.

Mechanics and fabricators rely on REDHORSE PERFORMANCE reducers for street performance builds, drag racing fuel systems, supercharger installations, and custom engine cooling circuits where port mismatches are common. NPT (National Pipe Taper) threading ensures leak-free connections when used with appropriate thread sealant or PTFE tape. This fitting pairs seamlessly with fuel rails, oil coolers, intercooler lines, and boost controllers. Installation requires only hand tools and basic plumbing knowledge; simply thread the male connector into your system's 1/2 inch port and attach your 1/4 inch hose or fitting to the female outlet. For professional results, apply quality thread sealant and torque fittings hand-tight plus 1/4 turn to avoid over-tightening the aluminum body.
