Union Couple Fitting - #10 x 3/8npt

The Union Couple Fitting - #10 x 3/8npt from MAGNAFUEL/MAGNAFLOW is a precision hydraulic connector designed for high-performance fuel system applications. This fitting is ideal for serious enthusiasts and professional mechanics who require reliable connections for custom fuel injection systems and turbo upgrades. It ensures a secure, leak-proof interface that modern fuel systems demand.

This union couple fitting features a dual-thread design—#10 on one end and 3/8" NPT on the other—allowing it to bridge incompatible hose or component ports without compromising flow dynamics. The 3/8" NPT side threads securely into fuel rails, carburetors, or pressure regulators, while the #10 AN port accepts standard braided stainless fuel line with a 37-degree flare seat. MAGNAFUEL/MAGNAFLOW's engineering ensures precise tolerances and materials that resist corrosion, which is critical in aggressive underhood environments.

This compact fitting (3.05 x 1.2 x 3.8 inches, weighing just 0.07 lbs) is essential for those integrating a programmable EFI system into a modified engine bay. It is particularly beneficial for applications involving fuel pressure regulation and custom fuel injection setups. With its robust design, this fitting is a reliable choice for any high-performance fuel system.
