GROCO 1/2" NPT 90° Bronze Fuel Valve

The GROCO 1/2" NPT 90° Bronze Fuel Valve (model FV-590) is a compact yet robust fuel isolation component purpose-built for marine fuel systems where reliability cannot be compromised. Whether you run a center console, cruiser, or displacement hull, this valve sits at the heart of fuel line management—controlling flow between your tank and engine with the dependability that separates a season of trouble-free boating from costly mid-water repairs.

Bronze construction and a 90° elbow configuration make it a marine industry standard for vessels that demand corrosion resistance and longevity in saltwater and freshwater environments alike. This fuel valve employs a sealed bronze body with a 1/2" NPT (National Pipe Thread) connection—the universal standard for marine fuel system plumbing—and the 90° elbow design eliminates the need for additional fittings or elbows downstream, reducing potential leak points and streamlining installation.

Boat owners performing fuel system upgrades, rebuilds, or maintenance will find the GROCO FV-590 essential. Its compact footprint and modest weight allow it to fit tight engine compartments without sacrificing flow or durability, while the simple ball-valve mechanism provides smooth, reliable on-off control with minimal maintenance.
