Forespar MF 847 Vented Loop - 1-1/8"

The MF 847 Vented Loop is an essential component for marine and boating systems, designed to prevent unwanted siphoning between tanks. Whether you're managing your marine toilet system or ensuring efficient engine cooling, this vented loop offers reliable performance and durability. Crafted from high-quality Marelon, the loop resists corrosion and withstands the harsh marine environment, ensuring long-lasting functionality. The integrated duckbill one-way valve effectively seals against water and fluid flow while allowing air to enter the system when not in use, even in the presence of particulate matter.
