MF 841 Vent Cap Assembly
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.
The Forespar Performance Products MF 841 Vent Cap Assembly is an essential component designed to prevent siphoning in marine toilet and engine cooling systems. Its vented loop allows air to enter the line when not in use, effectively stopping water or other fluids from siphoning from tank to tank, ensuring system integrity. Constructed from durable Marelon, this vent cap is resistant to corrosion, making it ideal for marine environments where exposure to moisture and salt can cause deterioration. The integrated duckbill one-way valve provides a reliable seal, even when particulate matter is present in fluids, maintaining optimal system performance. Easy to install and maintain, the MF 841 vent cap assembly offers a dependable solution for marine and engine cooling applications, ensuring fluids stay contained while allowing necessary airflow. Crafted with quality and longevity in mind, this vent cap is a versatile choice for boat owners seeking durable, corrosion-resistant components that enhance system reliability and safety.

The Trident Marin Extra Flex Corrugated Wet Exhaust hose works great. I had to replace the old hose coming from the generator muffler to the exhaust pipe going out the hull. The hose needed to be curved and the flex was perfect. Delivery was fast with no issues. Thank you
