Product Overview

MF 847 Vented Loop - 1-1/8"

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: 1-1/8" (28.57mm)
  • Height: 7" (177.8mm)
  • Width: 9" (228.6mm)

Expert Overview

The Forespar MF 847 Vented Loop, part number 903018, is a fluid management component designed to prevent siphoning between tanks. This device is suitable for marine toilet systems and engine cooling systems where unintended fluid transfer can occur. Its integrated valve system allows air to enter the line when not in use, which breaks the siphon, but seals effectively when fluid flows through. Constructed from Marelon, both the vent and loop are resistant to corrosion, enhancing durability in demanding environments. The duckbill one-way valve is engineered to maintain a proper seal even when particulate matter is present in the fluid. This vented loop addresses the practical need for reliable fluid isolation in marine and engine applications, helping to maintain system integrity and prevent operational issues caused by siphoning.
