Straight Adapter Fitting #8 x 1/2 MPT Black

The Straight Adapter Fitting #8 x 1/2 MPT Black by FRAGOLA is a precision hydraulic and fuel line connector engineered for systems requiring a transition between 8 AN (Army-Navy) male ports and 1/2 inch NPT (National Pipe Thread) male connections. This adapter serves as a critical junction component in high-performance fuel systems, hydraulic applications, and custom automotive builds where port size or thread-type mismatches must be resolved reliably. Built for environments where pressure integrity and leak-free performance are non-negotiable, this fitting is essential for mechanics, fabricators, and enthusiasts assembling complex fluid delivery networks.

Constructed from aluminum and finished in black anodize, this straight adapter combines lightweight durability with corrosion resistance suitable for both street and competition environments. The anodized finish protects against oxidation and enhances aesthetic consistency across modern fuel system builds, while aluminum construction keeps overall system weight minimal—critical in performance applications. The straight configuration ensures zero flow restriction and simplifies installation in tight engine bay layouts where 45-degree or 90-degree fittings would create fitment conflicts. FRAGOLA's precision manufacturing guarantees dimensional accuracy and thread concentricity, essential for achieving reliable seals across mixed-thread applications.

This fitting is ideal for fuel system builders upgrading carbureted or EFI engines, hydraulic system integrators, and custom fabricators who work with modular or sourced components from multiple manufacturers. Common applications include fuel pressure regulators, filter head assemblies, and manifold blocks requiring NPT inlets paired with AN outlet ports. The compact 1.5 x 1.5 x 4.1 inch profile accommodates space-constrained engine bays and equipment mounting locations. Installation requires standard line wrenches; proper use of thread sealant on the NPT end ensures pressure-tight performance across fuel, oil, and coolant systems operating up to typical aftermarket specification limits.
