GROCO 3/8" NPT Bronze Inline Fuel Valve

The GROCO 3/8" NPT Bronze Inline Fuel Valve (Model FV-375) is a dependable flow-control solution designed for marine, RV, and industrial fuel system applications where reliability and durability are non-negotiable. This inline fuel valve serves as a critical isolation and regulation point in fuel lines, allowing operators to quickly shut off or manage fuel flow with a simple handle rotation. Whether you're securing a fuel tank during maintenance, preventing siphoning, or managing fuel distribution across multiple systems, this valve delivers the consistent performance that experienced technicians and equipment owners trust.

Constructed from C83600 bronze—an industry-standard alloy chosen for its corrosion resistance and longevity in fuel environments—the valve withstands 400 WOG (working operating gauge pressure) without compromise. The selectable handle rotation feature allows flexible installation in tight spaces, while the full-flow design ensures minimal pressure drop during operation. PTFE (Teflon) seats and seals provide chemical compatibility with gasoline, diesel, and biodiesel fuels, while stainless steel handle and hardware resist oxidation and maintain smooth actuation over years of use. The integrated mount foot simplifies installation on panels, bulkheads, or engine compartments, eliminating the need for additional brackets.

Boaters, RV enthusiasts, and industrial maintenance professionals rely on this valve for auxiliary fuel tank isolation, fuel transfer systems, and emergency shutoff applications. The 3/8" NPT (National Pipe Thread) connection accommodates standard fuel line fittings found on most marine and automotive fuel systems. Installation is straightforward—simply thread the valve inline with your existing fuel line and secure using the provided mount foot. This compact unit weighs just 0.55 pounds and measures 3 x 2 x 5 inches, making it ideal for space-constrained engine bays and fuel compartments where every inch counts.
