Forespar Performance Products MF 841 Vent Cap Assembly for Marine and Engine Systems

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 for marine toilet and engine cooling systems. Crafted from durable Marelon, this vented loop prevents fluid siphoning between tanks by allowing air to enter the line when not in use, while effectively sealing during fluid flow. Its corrosion-resistant construction ensures long-lasting performance even in harsh marine environments. The integrated duckbill one-way valve is engineered to seal properly despite the presence of particulate matter, maintaining system integrity and preventing leaks. Easy to install and maintain, this vent cap assembly is suitable for various applications requiring reliable fluid management and ventilation. Its compact size and robust design make it an ideal choice for boat owners and marine technicians seeking a dependable solution for fluid control systems.
