Straight Adapter Fitting #8 x 1/4 MPT Black

The Straight Adapter Fitting #8 x 1/4 MPT Black by FRAGOLA is a critical hydraulic and pneumatic line component designed for mechanics and fabricators who demand precision fluid transfer in high-performance automotive systems. This fitting serves as a direct connection point between AN-sized hose or tubing (#8 designation) and NPT-threaded ports (1/4 MPT male thread), making it indispensable for fuel systems, brake circuits, coolant lines, and custom plumbing in street rods, race cars, and engine builds. Whether you're routing fuel from a custom tank, integrating a turbo intercooler system, or building a complete brake line architecture, this adapter eliminates the need for makeshift solutions and ensures leak-free operation under pressure and vibration.

FRAGOLA's engineering delivers a straight-port design that minimizes turbulence and pressure loss, critical when managing fuel delivery to carburetors or EFI systems, or when bleeding brakes in tightly packaged engine bays. The black anodized aluminum construction provides corrosion resistance while maintaining lightweight characteristics essential for performance vehicles, and the precision machining ensures a secure, vibration-resistant connection. The #8 size accommodates standard -8 AN hose, while the 1/4" male pipe thread (MPT) accepts factory or aftermarket NPT-threaded receivers—a common pairing in adapting modern fuel injection components, transmission cooler lines, or catch-can drain ports to existing mechanical systems.

Professional fabricators, engine builders, and DIY enthusiasts benefit from stocking this fitting for rapid system assembly and modification without trial-and-error hose routing. It's particularly valuable when integrating aftermarket fuel systems into vintage platforms, adapting modern cooling solutions to classic chassis, or simplifying plumbing in engine swaps where NPT ports exist alongside AN infrastructure. The compact 3.45-inch length and minimal 0.04-pound weight make installation straightforward in confined spaces, and its universal compatibility with any system using #8 AN hose and 1/4" NPT connections ensures reliable performance across decades of automotive designs and power levels.
