Vented loops are commonly used in the marine toilet system and engine cooling system. 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. Molded in Marelon, neither vent nor loop will corrode. The duckbill one way valve is designed to seal properly if particulate matter is present in fluids.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBarb Size: 1-1\/2\" (38.1mm)\u003c\/li\u003e\n\u003cli\u003eHeight: 5-1\/4\" (133.35mm)\u003c\/li\u003e\n\u003cli\u003eWidth: 7-3\/4\" (196.85mm)\u003c\/li\u003e\n\u003c\/ul\u003e \u003c!--- cis2:m2lumZRk ---\u003e\n\u003cp\u003eThe Forespar Performance Products MF 840 Vented Loop is an essential component designed to prevent siphoning in marine and engine cooling systems.
