This 6 foot long CPAP hose is our most popular hose. It is 19mm in diameter with 22mm rubber cuff ends and is compatible with many CPAP and BiLevel machines. There isn't a better value CPAP hose out there.
The ClimateLine Tubing has an internal heated coil and mask temperature sensor that eliminates rainout in the hose. Climate Control algorithms measure temperatures from the humidifier to prevent condensation from forming. This tubing ONLY work with S9 CPAP Machines.
