Bistras Oxygen Adapter Enrichment Port Connector fits CPAP Tubing Hose Model 1642 (1)

works well, fits most cpap machines. Allows you to inject O2 into the system without spending a ton on an adapter from the cpap manufacturer.

worked great with my Rezmed 10 machine hose. Nipple was a little on the large side which required me opening the inlet tubing with sharp pointed needle nose pliers in order to to get it mounted correctly.

Godsend and at a good price. These were hard to find despite their need. I'm glad it came in a 2 pack also. The first one never has broken, but it's still good to know I have a spare. I am pretty rough on my BiPap hose and oxygen tubing. I like to flip and flop throughout the night while sleeping and all the tubing sometimes get caught up on my nightstand and get tugged and pulled. This this oxygen connector has held up AMAZING WELL. Would highly recommend.

I use these for my daughter’s ventilator. The plastic is heavier than the ones we get from her DME and the oxygen tubing fits better on these. We’ve been washing a reusing these for a while and they’re still like new. She’s an active kid and hasn’t broke one yet!

Perfect fit with the CPAP hoses and O2 line

Works perfectly

The fitting is perfect but I haven’t tried it yet. I am worried that it doesn’t have check valve and hope it works well with my CPAP

These adapters are much better made than the ones that come from the oxygen supplier. The plastic is stronger, and they have a good seal. I like that I have extra should one break too. I recommend these.
