It is suitable for more than 99% of oxygen pumps to stop flow, and the oxygen pipe with an inner diameter of 4mm is universal.

Function of check valve - when the oxygen pump is placed below the water level of the fish tank (such as on the bottom cabinet or desktop),when the oxygen pump stops working due to power failure or other reasons, the fish tank water may flow back into the oxygen pump, resulting in water inlet damage or burning of the oxygen pump. The check valve can solve this problem.
