This Heated Micro-Flexible Tubing is designed exclusively for use with Dream-Station 2 Series CPAP. It is the lightest, most flexible heated tubing. With ultralight Micro-Flex Tubing you can sleep in any position without worrying about drag, or heavy tubing sitting on your bedsheets and body. Micro-Flex CPAP Tubes include handy secure-click mechanism at the end so that the tubing is exceptionally secure; but easy to attach and detach as well. At the end of this Micro-Flex Tubing is a PR12 Adapter which makes the tubing compatible with any standard CPAP from any manufacturer. If you use one of more modern like the Dream-Wear or Full Face, you can remove the quick release connector from the and the standard adapter from your Micro-Flex Tubing and the will click directly onto the tube. It's a great way to create an almost seamless (and more lightweight).
