The Nipple Nut Adaptor, aka Christmas Tree Adapter, is used to bypass the water bottle to attach the long hose or long cannula directly to the O2E2 Machine. We advise against this as it may dry out nostrils.
- Tapered nut and nipple assembly permits secure tube connections
- Fits easily to standard oxygen concentrators
- Made of high-grade plastic
- High resistance to breakage
Prolonged use may lead to excessive drying of nostrils
