Fisher Paykel Mask Swivel Connector #900HC438

This little accessory is a must-have for easy connecting/disconnecting if you travel a lot with your Cpap. It fits onto the end of the tube that connects with the Cpap machine, and eliminates the time-consuming wrangling with the rubber tube tip that fits so snuggly on the Cpap machine. With this little connector, you can slide it on and off very easily, yet it stays put while you're asleep. Buy 3 of them when you order it -- for some reason they do show tiny cracking after a while. Also, when you get it, I'd advise that you wrap the outside of the end that fits on the machine with scotch tape to make it last longer.

Price was good, shipping was timely, head harness is hard to use the way it is designed but it works.
