Jabsco 1" Vented Loop

The Jabsco 1" Vented Loop is an essential safety component for any marine cooling or raw water system, designed to prevent siphoning and protect your engine from catastrophic water damage. This device is crucial for boaters who want to avoid costly repairs due to water intrusion through raw water intake lines.

The 1-inch diameter fitting integrates directly into your raw water intake line, sitting above the waterline to create an air break in the system. When the engine shuts down, the vented loop allows air to enter the circuit, breaking the siphon and forcing water to drain safely from the engine block. Constructed from corrosion-resistant marine-grade materials, it withstands harsh conditions without degradation.

This vented loop is compatible with any raw water cooling system using standard 1-inch barbed or threaded connections, making it suitable for freshwater, brackish, and saltwater applications. Installation is straightforward, requiring it to be mounted at least 12 inches above the waterline, ensuring reliable performance for saltwater anglers and charter captains alike.
