Check valves are an essential piece of equipment when implementing CO2 injection or air pump in a planted aquarium tank. Check valves are used to prevent the backflow of water to air pumps and CO2 regulators. The Precision Check Valve is an extremely durable piece of equipment constructed from solid materials that is designed to handle high pressure, preventing aquarium water from siphoning into parts it shouldn't and increasing overall product longevity.
Unlike plastic CO2 check valves that deteriorate due to gas pressure and easily broken glass pieces, this precision check valve provides extreme durability and is ideal for longterm use without having to be replaced every few months.
