903000 - Forespar Performance Products Forespar MF 840 Vented Loop - 1/2"

MF 840 Vented Loop - 1-1/2"

Installing one of our vented loops will ensure that fluids will not siphon from tank to tank. 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. 

Specifications:

• Height: 5-1/4" (133.35mm)
• Width: 7-3/4" (196.85mm)

The Forespar MF 840 Vented Loop, part number 903000, is designed to prevent fluid siphoning between tanks in systems where this risk is present. This component is commonly integrated into marine toilet systems and engine cooling systems to maintain fluid isolation. Its design incorporates a simple valve system at the top of the loop, which allows air to enter the line when the system is not in use. This mechanism effectively seals once water or other fluids begin to pass through, preventing backflow. Constructed from Marelon, both the vent and the loop are resistant to corrosion. The integrated duckbill one-way valve is engineered to maintain a proper seal even when particulate matter is present in the fluid stream. This product is suitable for IT buyers managing infrastructure in marine or similar environments requiring reliable fluid management and siphoning prevention.
