GROCO 1" Bronze Tri-Flanged Ball Valve/Seacock

The GROCO 1" Bronze Tri-Flanged Ball Valve/Seacock is an essential component for marine applications, particularly for cruising boats, commercial vessels, and serious fishing platforms. This valve serves as a critical safety feature, providing through-hull isolation and flow control to prevent catastrophic flooding during emergencies or equipment failures.

Constructed from marine-grade bronze, this valve is engineered to withstand the corrosive effects of saltwater, ensuring long-lasting reliability. Its tri-flanged design allows for even stress distribution and simplifies installation into existing through-hull systems. The full-port ball mechanism guarantees unrestricted flow when open and a positive shutoff when closed, eliminating concerns about gradual leakage.

GROCO seacocks are trusted by experienced vessel operators for applications such as raw water cooling loops, bilge pump discharge, and emergency isolation. The 1-inch connection size is compatible with common through-hull fittings found on most recreational and commercial hulls, making it a versatile choice for various marine setups.
