MF 839 Vented Loop - 1-1/4"
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:
The Forespar MF 839 Vented Loop is a fluid management component designed to prevent siphoning between tanks in marine and engine cooling systems. This 1-1/4" vented loop integrates a simple valve system that allows air to enter the line when inactive, preventing unintended fluid transfer. When fluid passes through, the valve seals to maintain system integrity. Constructed from Marelon, both the vent and loop are resistant to corrosion, ensuring durability in demanding environments. The incorporated duckbill one-way valve is engineered to seal effectively even when particulate matter is present in the fluid stream. This product, part number 903011, is suitable for IT professionals and businesses managing marine or industrial fluid systems where reliable siphoning prevention is critical for operational stability and compliance.
Its primary function is to prevent fluids from siphoning from one tank to another. It achieves this by allowing air into the line when not in use, which breaks the siphon.
Vented loops like the MF 839 are commonly used in marine toilet systems and engine cooling systems to manage fluid flow and prevent siphoning.
The vent and loop are molded in Marelon, a material chosen for its corrosion resistance, which is beneficial in marine or other corrosive environments.
The barb size for the Forespar MF 839 Vented Loop is 1-1/4 inches (28.57mm).
