Glass Check Valve ¼" - Ultum Nature Systems

Glass Check Valves are designed to handle high pressure and prevent aquarium water from siphoning. Backflowing water 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.
