Check Valve for Airline Tubing

Whether you have a freshwater or marine aquarium, Check Valves are a must-have accessory. Their easy-to-read directional arrow helps you determine the flow direction, making installation a breeze. The clear window feature allows you to easily monitor the valve’s functionality and know when it’s time for a replacement. With two valves included in each package, you’ll have everything you need to keep your aquarium running smoothly. If the electrical power fails, the water will not back flow from the aquarium into the pump.

Package includes 2 Check Valves.
