Forespar Vented Loops

Vented loops are commonly used in marine toilet systems, bilges, and engine cooling systems. With the simple inverted duckbill valve system incorporated into the top of a Forespar vented loop assembly air can enter the line when not in use, but is sealed out when water or other fluids are present. Even better, the molded in glass-reinforced Marelon means neither the vent or the loop will ever corrode – so you can be sure this loop is built to last.
