Glass CO2 Non Return Valve

Glass CO2 Non Return Valve

Once CO2 supply is stopped, aquarium water often flows backward into the tube toward the regulator or reactor.  To prevent water from entering a regulator and causing serious damage or filling your reactor you can use this Glass CO2 Non Return Valve.  Standard plastic valves lose their function due to wear and tear of the internal bladder or membrane.

This all glass, handmade non-return can be used indefinitely, and makes an elegant addition to your aquarium.  It is designed to be installed in-line with the CO2 tube.
