Check Valves | A2Z Ozone

Regular price $ 7.99 Sale price $ 14.99

Check Valve: 1/4" or 5/16" (inches)

Typically used with water applications, the check valve is handy for preventing water damage to the ozone generator by blocking water from seeping back into the unit. The arrow shows the direction of ozone flow from the nozzle to water. To ensure no water comes back through the tubes to your unit, please replace any check valves after 6 months of use. 

Choose your size:

1/4" - Aqua-Series

5/16" - MP-Series, SP-Series, S-Series, Z-Series

Please select according to the diameter of your tubing.

They are available as a set of 2 check valves + 1 free promotional check valve. The 1/4" purple check valves are also available as a set of 5.
