Plastic Check Valve for aquarium airline

Aquarium Check Valve

This check valve is designed to protect your tank's air pump against water damage, effectively keeping it in play for longer and keeping your fish healthier. The unique design helps prevent water back-siphoning in the event of a power outage or air pump failure, which can compromise the quality of your equipment and the safety and health of your fish. To install the Check Valve, simply connect it in-line to the air tubing in-between your air pump and your aquarium.
