Forespar Vented Loop 5/8" MF-843 Laser Clear insulating coverMF 843 Vented Loop . 625" 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 into the top of the loop allows air to enter the line when not in use, yet effectively seals as water and other fluids pass through. molded in Marelon, neither loop nor vent will corrode.
