Stainless Steel Aquarium Air Line Control Valve

An inline air control valve for tuning airflow in an aquarium air line. The barbed connectors take a length of standard airline at each end, and the lever tap lets you restrict, increase or fully shut off the air passing through, so you can set the exact bubble rate at an air stone, sponge filter or air-driven ornament without adjusting the pump or unplugging anything. It is made from stainless steel for corrosion resistance in damp aquarium conditions, with a smooth lever for repeatable adjustment and barbed ends that grip standard airline tubing securely. It works well paired with an air pump that runs stronger than a single device needs, letting you trim the flow back to a precise, quiet level. Key features: Stainless steel construction, corrosion-resistant for aquarium use Inline lever tap to fine-tune or fully shut off airflow on a line Barbed connectors at both ends for standard aquarium airline tubing Adjust bubble rate without touching the air pump Compact and simple, with no maintenance required What's in the box: 1 × Stainless Steel Aquarium Air Line Control Valve Installation: Cut your air line where you want the control point, between the pump and the air stone or sponge filter. Push the airline from the pump side onto one barbed end of the valve, and the airline running to your device onto the other end. A check valve between the pump and this valve is recommended to prevent water back-siphoning if the pump stops. Turn the lever to set the airflow to the bubble rate you want, or fully closed to stop that line.
