Swivel Connector for Oxygen Tubing

It works well good.

I am a belt & suspenders type so over the years I have picked up spare Respironics BiPAPs, Oxygen Concentrators, masks, etc. as potential backups. I needed additional connectors to use if it was necessary to use spare BiPAPs for other family members because of the present Corona virus problem. This connector works to extend oxygen tubing or for connecting a cannula.

Excellent
