Fits my heated hose Philips Respironics System One
These things are made from fairly soft plastic; the oxygen connector pipe will shrink and collapse after about 6 months just from having the clear plastic hose on it. Still, 5 bucks for a simple part that keeps my super expensive bipap working with the supplemental oxygen, for half a year, it's a no-brainer. It's a perfect fit between the hose end and my Fisher Paykel nasal mask.<br /><br />I wish they made a right angle connector too, so the O2 line could lie closer to the BiPap hose, but I get by with this one just fine.
