903003 - Forespar Performance Products Forespar MF 843 Vented Loop - 5/8"

MF 843 Vented Loop - 5/8"

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:

• Barb Size: 5/8" (15.87mm)
• Height: 4-1/2" (114.3mm)
• Width: 4" (101.6mm)

The Forespar MF 843 Vented Loop is a component designed to prevent fluid siphoning between tanks in systems where this could be an issue. It is particularly relevant for marine toilet systems and engine cooling applications, where maintaining fluid levels and preventing unwanted transfer is critical. The unit incorporates a simple valve system that allows air to enter the line when the system is inactive, breaking any potential siphon. When fluid flows, the valve seals to ensure proper operation. Constructed from Marelon, both the vent and the loop are resistant to corrosion, contributing to system longevity. The duckbill one-way valve is engineered to maintain its seal even when particulate matter is present in the fluid, enhancing reliability. This 5/8" vented loop, part number 903003, offers a practical solution for fluid management in demanding environments.
