GROCO 1-1/2" NPT Bronze In-Line Ball Valve

The GROCO 1-1/2" NPT Bronze In-Line Ball Valve is an essential component for serious boaters and marine system owners. This valve is ideal for managing through-hull plumbing, isolating fuel lines, and controlling water flow to marine heads or galleys. Its reliability is crucial for maintaining safety and operational efficiency, especially when far from the nearest dock.

Constructed from marine-grade bronze, the GROCO in-line ball valve is designed to resist corrosion and oxidation, making it suitable for both saltwater and freshwater environments. The 1-1/2" NPT connection standard ensures compatibility with existing marine plumbing systems. Its full-port ball design minimizes flow restriction and pressure drop, which is vital for running multiple systems efficiently.

Trusted by charter operators, commercial fishermen, and recreational cruisers, this valve provides independent isolation capability for raw water cooling circuits, waste discharge lines, and fuel transfer systems. Weighing 3.5 lbs and compact in its 6 x 3 x 8-inch footprint, it fits neatly into tight engine compartments without taking up valuable locker space. The manual lever handle offers instant shutoff with clear tactile feedback.
