Hose Adapter

I'm hyper sensitive to air temperature on my CPAP machine, so I printed a hose adapter so that I can determine where my air is coming from to supply the machine. Most the time the hose is in an open window, or pointed towards my air conditioner. I have a Resmed 10 airsense. This is the hose I use. It will screw into the adapter. 2.5 inch hose https://www.amazon.com/gp/product/B01M35BE8D/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
