GROCO Bronze Vented Loop for 2-Inch Hose

The GROCO Bronze Vented Loop for 2-Inch Hose is an anti-siphon fitting for compatible marine sanitation, cooling-water, or exhaust plumbing that uses 2-inch hose. It allows air into the line to break siphon action while its valve is built to prevent normal air and odor escape through the vent opening.

The oversized vent valve can be removed for inspection and cleaning, supporting dependable anti-siphon protection in service. A threaded cap can accept a barb fitting when the installation requires the vent to be routed overboard, including supported exhaust-system applications.

Confirm hose size, loop elevation, system application, mounting orientation, vent routing, and service access before installation. Position the loop at the required height above the waterline, follow GROCO plumbing guidance, and inspect the vent valve periodically for salt, debris, or other blockage. See the rest of our bilge and water pumps.
