Product Overview
Install a Marelon Vented Loop to ensure fluids will not siphon from tank to tank. Molded from lightweight, high-strength Marelon, these Vented Loops are highly resistant to corrosion, UV degradation and abrasion. Commonly used in marine toilet and engine cooling applications, the simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes through. Since they are made from Marelon, neither vent nor loop will corrode. The duckbill one-way valve is designed to seal properly if particulate matter is present in fluids. Marelon Vented Loops feature hose barbs on both ends (size given as inside diameter or ID).
