GROCO 1-1/4" Bronze In-Line Check Valve

The GROCO 1-1/4" Bronze In-Line Check Valve is a marine-grade one-way flow control device designed to prevent backflow in through-hull installations, raw water cooling systems, and bilge pump discharge lines. This valve is essential for boaters who want to protect their engines from seawater or coolant flowing backward, which can lead to severe corrosion or damage.

Constructed from durable bronze, the CV-125 offers superior resistance to saltwater corrosion compared to steel or cast iron alternatives. Its internal flapper design allows for smooth flow in one direction while sealing tightly when backflow pressure occurs. With precise engineering, this check valve ensures reliable performance in various marine applications.

Ideal for anglers and cruising boaters, this valve is particularly beneficial on raw water cooling discharge lines, preventing seawater from siphoning back into the engine block. It is also effective in through-hull bilge or livewell drain systems, where backflow can cause significant issues. The compact design allows for easy installation in tight spaces, making it a valuable addition to any marine setup.
