Straight Adapter Fitting #3 x 1/8 MPT

The Straight Adapter Fitting #3 x 1/8 MPT from FRAGOLA is a precision hydraulic and fuel system connector designed to bridge incompatible port types in high-performance and industrial applications. This adapter fitting solves common plumbing challenges where AN (Army-Navy) male ports need to connect to NPT (National Pipe Thread) male ports, eliminating the need for custom fabrication or system redesigns. Whether you're building a custom fuel system, upgrading hydraulic lines, or integrating aftermarket components into existing manifolds, this straight adapter ensures leak-free, reliable connections in demanding environments.

Constructed from aluminum with blue anodized finish, the Straight Adapter Fitting #3 x 1/8 MPT delivers both durability and corrosion resistance in under-hood and outdoor installations. The blue anodizing provides enhanced surface protection while maintaining excellent visibility for system identification and maintenance. The #3 AN male port accommodates standard -3 hose and fitting configurations, while the 1/8 inch NPT male thread accepts industry-standard pipe fittings commonly found in fuel injection controllers, manifolds, and gauge blocks. The straight geometry eliminates flow turbulence compared to 90-degree alternatives, reducing pressure drops and ensuring consistent system performance.

This adapter is ideal for automotive enthusiasts, custom fabricators, and fleet maintenance professionals who need dependable port conversion without welding or thread-chasing operations. Installation requires only standard wrenches and thread sealant (PTFE tape or pipe dope recommended for NPT connections). The lightweight design—just 0.01 lbs—makes it suitable for weight-sensitive applications including racing fuel systems, aircraft auxiliary systems, and portable hydraulic equipment. FRAGOLA's reputation for precision engineering ensures this fitting meets SAE J518 CODE 61 standards for AN connections and NPT specifications for seamless integration into OEM and aftermarket systems.
