GROCO 1-1/4" Bronze Flanged Full Flow Seacock

The GROCO 1-1/4" Bronze Flanged Full Flow Seacock is an essential marine plumbing component for serious boaters and anglers, designed for through-hull water intake and discharge applications. This seacock is perfect for various uses, including raw-water cooling systems, livewell circulation, and transom drains, providing the reliability needed for extended time on the water.

Constructed from cast bronze, this seacock offers excellent corrosion resistance in saltwater and brackish environments, ensuring longevity below the waterline. Its full-flow ball valve design minimizes pressure drop and sediment trapping, allowing for consistent water delivery without the limitations of restrictive gate or needle mechanisms. The flanged connection integrates seamlessly with standard marine hose fittings and through-hull installations, while the lever handle provides quick on-off control, even in challenging conditions.

GROCO's reputation for engineering excellence means this seacock is a trusted choice for anglers upgrading livewell systems, cruisers replacing aging through-hull valves, and diesel mechanics servicing cooling circuits. Installation is straightforward with standard marine epoxy or sealant, requiring no specialized tools. This versatility makes the GROCO seacock a professional choice for a wide range of marine applications.
