Straight Adapter Fitting #12 x 3/4 MPT Black

The Straight Adapter Fitting #12 x 3/4 MPT Black is a precision hydraulic and pneumatic connection component engineered for systems requiring reliable AN-to-NPT port transitions. Manufactured by FRAGOLA, this straight adapter is designed for technicians, engineers, and equipment builders who need dependable fluid or air line integration without flow disruption. Whether you're assembling custom hydraulic circuits, restoring classic performance vehicles, or installing aftermarket fuel systems, this fitting provides the bridge between industry-standard 12 AN male connections and standard 3/4-inch NPT male ports.

Constructed from aluminum and finished with black anodized coating, the straight adapter resists corrosion while maintaining a lightweight profile ideal for weight-sensitive applications. The black anodized surface provides both aesthetic consistency in custom builds and enhanced durability against oxidation and chemical exposure. The straight design—as opposed to 45° or 90° configurations—allows direct, inline connections that minimize turbulence and pressure drop while simplifying installation in confined spaces. The 12 AN male end accepts standard AN hose fittings, while the 3/4 in NPT male port threads directly into female NPT ports on pumps, filters, manifolds, and other system components.

This adapter excels in racing fuel systems, hydraulic brake upgrades, transmission cooler installations, and industrial fluid-power applications where cross-port compatibility is essential. Technicians frequently specify straight adapters when existing NPT-ported components must integrate with modern AN braided hose systems. Installation requires thread sealant appropriate to your fluid type; the compact 4.2-inch length and 1.5-inch width fit easily into engine bays and tight component clusters. Verify your system's pressure rating and fluid compatibility before installation to ensure optimal sealing and longevity.
