Glass Check Valve for CO2 or Air-Stone/Bubblers

Check valves are used to prevent liquid back flow on an airline or CO2 tubing.  When using either an air pump or CO2 system, it is important to use a check valve  to make sure water doesn't leak from your aquarium and into your air pump or CO2 regulator.  Water or any liquids can cause damage to an air pump as well as the needle valve of a regulator
