10PCS Red Oxygen Pump Air Line Check Valve Aquarium Air Check Valve Fish Tank Oxygenator One Way Air Check Valve for Aquarium Supplies Accessories Equipment
Specification:Made of hard plastic, reusable, durable and aging resistant.
Dimensions: Air hole diameter is 0.16¡°, check valve length is 2.1¡±.
Connection Method:There is a small arrow on the body of the air check valve, the head of the arrow is the output end, which is connected to the tube on the air stone side, and the end of the arrow is the input end, which is connected to the hose on the air pump side.
Features:When the oxygen pump is placed below the water level of the aquarium (e.g., on the bottom cabinet or desktop), a power outage or other reasons that cause the oxygen pump to stop working may cause the aquarium water to flow backward into the air pump, resulting in water damage or burned out of the air pump. A non-return valve can solve this problem! The use of a non-return valve to prevent water from entering the air pump is an essential accessory for the air pump.
Function:This aquarium air pump check valve protects the air pump and prevents the water in the aquarium from back siphoning into the air pump during a power outage, damaging the air pump and shortening its life. This one-way valve is very suitable for aquariums
