GROCO 1/2" NPT Bronze Inline Fuel Valve

The GROCO 1/2" NPT Bronze Inline Fuel Valve (Model FV-500) is a marine-grade fuel system component engineered for reliable control of fuel or water flow in demanding offshore and freshwater applications. Built from C83600 bronze—an alloy selected for superior corrosion resistance in salt and brackish environments—this inline valve delivers full flow capacity with the durability required in maritime service where fuel system integrity directly impacts vessel safety and performance.

Key specifications reflect professional-grade engineering standards. The valve features a 1/2" NPT (National Pipe Thread) connection, the industry standard for marine fuel systems. Its 400 WOG (Working Operating Gauge) rating provides substantial safety margin for typical fuel system pressures encountered on powerboats and yachts. PTFE (polytetrafluoroethylene) seats and seals ensure chemical compatibility with modern fuel formulations while maintaining a tight shutoff over extended service intervals. The stainless steel handle and hardware resist corrosion where bronze alone would be insufficient, while the selectable handle rotation allows installation in confined spaces. A mount foot is included for secure deck or engine-room installation, and UL listing for both fuel and water applications confirms compliance with marine safety standards.

This valve is specified for marine fuel systems where isolation, maintenance shutoff, and reliable on-demand control are essential. Boat builders, marine mechanics, and vessel owners select GROCO inline fuel valves when standard plastic isolation valves prove inadequate for saltwater environments. The bronze construction and full-flow design make it equally suitable for raw-water cooling systems and other marine applications requiring durable, corrosion-resistant isolation.

GROCO is recognized in the marine industry for producing valve components that prioritize longevity and reliability in high-corrosion environments. The FV-500 represents the standard approach to inline fuel control on quality-built vessels where component lifespan and system dependability directly correlate to ownership cost and uptime.
