"The newer cpap machines are very sensitive to hose size so if you use and have set for standard hose size while adding this fitting your machine will not operate properly as the inside of this fitting is to constrictive. If you use new smaller hose with machine set on that it works fine. They need to make the fitting with same size center opening as the inside diameter of old style tubing as that would work with either size hose."

"I purchased this to conect my new light weight hose to old hose, thinking I would need a new conector for that, but wouldnt connect between those two hoses. So I am just going to keep it ... I wish when I bought the light weight hose that it said that I didnt need a coupler swivel between the hoses."
