Collection: Fittings

GROCO's E-Valve electric flanged seacocks give boaters remote control over through-hull valves, so you can open or close raw water intakes and discharge lines from a switch panel rather than reaching into a tight locker or bilge compartment. The flanged design mounts directly against the hull for a stable, low-profile installation, and bronze construction holds up in saltwater service over years of use. These are kit products, meaning they include the components needed for a complete install, which makes them well suited for refit projects as well as new builds.

The two key decisions before buying are size and voltage. GROCO offers these valves in pipe diameters from 3/4 inch through 3 inches, so measure your existing through-hull fitting or hose ID carefully before ordering, since a mismatch means the valve will not seat correctly. Each size comes in both 12V and 24V versions, and you need to match the valve to your boat's DC electrical system. Larger diameter valves typically suit higher-flow applications like engine cooling or livewell feeds, while smaller sizes cover bilge pump and cockpit drain circuits.
