Ozone-resistant one-way valve

This little one-way valve should be installed on the air tube that runs from the ozonator to the ozone injecteur. It push-fits into 1/4-inch flexible pipe.

Del Ozone has slightly modified this valve, which used to be green on one side and white on the other. It is all white and, according to the manufacturer, even more reliable than its predecessor. Please also note that the white valve shipped may be slightly different from the one displayed on our site, as Del Ozone sells several models - all interchangeable - under the same part number.
