Glass Check Valves are designed to  handle high pressure and prevent aquarium water from siphoning. Backflowing w ater can cause permanent damage to air pumps and CO2 regulators. Unlike plastic CO2 check valves that deteriorate due to gas pressure, its high-quality glass design allows for longterm use without having to be replaced every few months. Cost effective yet aesthetically pleasing, this CO2 Glass Check Valve can save over a hundred dollars (or more) of equipment.
