12mm Non-Heated Tubing?

[StratCat48]

Dream Station 2 user here and I've been using a Philips Heated 12mm tube (HT12) which is super flexible and non-obtrusive. The DS2 when either a 15mm or 12mm heated tube is connected will automatically set the CPAP tube size setting to the appropriate size tube connected. If a non-heated standard tube is used, there are 22mm, 15mm, and 12mm tube sizes selectable in the settings. Lately I have the heat turned off for the tube as I don't experience rainout with the overhead tube hanger that I use. I'd like to find a 12mm non-heated tube to try, but they seem non-existent in my searches.

Has anyone come across any 12mm non-heated tube?

I have not seen 12mm, but Resmed #36810 is a high quality slim 15mm non heated tube.
I have used this often, especially with my travel machine, but also with my Airsense 10 and 11 during times when I don't need the heated tube.

Many of the generic tubs are of extremely poor quality. Often that will leak by the cuffs. The Resmed is durable, and is reasonablly flexible.
