About this product

The Forespar MF 839 Vented Loop is designed to prevent fluid siphoning in marine applications such as toilet and engine cooling systems. It features a simple valve mechanism at the top of the loop that allows air to enter the line when the system is inactive and seals securely when fluids pass through. Constructed from corrosion-resistant Marelon, this unit includes a duckbill one-way valve engineered to maintain a proper seal even if particulate matter is present in the fluid.
