Does the ClimateLineAir Oxy tubing fit the S9 CPAP machine?

No, the ClimateLineAir Oxy tubing does not fit the S9 machine.

You would require the ClimateLine Max that has an orange adaptor on the end of the hose which will clip into the back of your machine when you rotate it 90 degrees. The types of tubes are typically used for supplemental oxygen and can be blocked off with a small cap (included) when it is not in use.
