GROCO 1" NPT Bronze In-Line Ball Valve

The GROCO 1" NPT Bronze In-Line Ball Valve is a marine-grade shut-off valve designed for reliable performance in both saltwater and freshwater applications. This valve is ideal for managing through-hull fittings, bilge systems, and raw water cooling lines, providing dependable flow control when needed. Built by GROCO, a trusted name in marine hardware, it meets the demands of boaters who require equipment that can withstand challenging conditions.

Constructed from bronze, this valve offers superior corrosion resistance in salt spray environments, making it a critical choice over standard steel valves for coastal vessels. The 1" NPT (National Pipe Thread) connection is compatible with industry-standard hose adapters and fittings, ensuring seamless integration with most marine plumbing systems. The in-line ball design allows for full port flow with minimal pressure drop and features a quarter-turn operation for quick isolation.

Anglers and cruising boaters utilize these valves to isolate raw water intake lines during winter layup, preventing freeze damage and corrosion. Commercial fishermen and charter operators depend on them for routine maintenance without the need for hauling out. With a weight of 1.65 lbs, this valve installs easily in tight engine compartments or bilge spaces without adding significant weight.
