GROCO 1/2" NPT Bronze 3-Way Valve

The GROCO 1/2" NPT Bronze 3-Way Valve is an essential fluid management component designed for marine, RV, and industrial plumbing systems where multi-directional flow control is required. This bronze three-way valve excels in applications requiring selective routing of water, fuel, or other compatible fluids between multiple ports. Its intuitive handle-pointed design and center-off position make it an ideal choice for operators who need reliable, straightforward flow direction without complex actuators or solenoid controls.

Built from durable bronze construction, this valve offers superior corrosion resistance in saltwater and freshwater environments, making it particularly valuable for marine applications. The handle rotates through a full 180-degree arc, allowing users to switch flow direction or shut off operation with a single, intuitive movement—the handle always points toward the active flow path. The included mount foot provides secure installation on bulkheads, tank tops, or cabin walls, while full-flow design minimizes pressure drop across the valve body. At just 1 pound and measuring 4 x 2 x 6 inches, the compact footprint fits easily into confined spaces typical of marine and RV installations.

This valve is particularly beneficial for applications involving tank selector systems, where operators must route fluids between multiple sources or destinations without power requirements. Liveaboard boaters, RV owners, and water system technicians appreciate the mechanical reliability and zero-maintenance operation of this design. The 1/2" NPT threaded ports provide standard compatibility with common marine and industrial hose fittings and pipe adapters, simplifying integration into existing plumbing networks. Installation requires only basic hand tools and basic plumbing knowledge, making replacement or upgrade projects straightforward for both professionals and experienced DIY users.
