The Dymax Check Valve is a one-way valve that prevents water from flowing back into an air pump or CO2 regulator.
Air or CO2 can only flow through the valve in one direction only.
This protects your equipment from potential water damage if the air pump or CO2 regulator is turned off.
The Dymax Check Valve is easy to install and use.
Simply install on your air hose or CO2 line.
It is compatible with both freshwater and saltwater aquariums.
