Overview

Vented LoopsType

Help prevent fluid from siphoning between tanks with the Forespar MF 840 vented loop. Used in marine toilet and engine cooling systems, it admits air into an idle line and seals when fluid flows through.

Key features

  • Air admission interrupts siphoning when the line is not in use.
  • The valve closes during fluid flow to keep the loop sealed.
  • Marelon construction keeps both the loop and vent free from corrosion.
  • A one-way duckbill valve is made to maintain its seal even when fluid contains particulate matter.
