Ensures that fluids will not siphon from tank to tank. Commonly used in marine toilet systems and engine cooling systems. Simple valve system in top of loop allows air to enter line when not in use, yet effectively seals as water or other fluid passes through. Molded in glass-reinforced Marelon, neither vent nor loop will corrode. Duckbill one way valve is designed to seal properly if particulate matter is present in fluids. Barb size 3/4", 4-1/2" x 3-3/4".
