Oxygen adapters are attachable components that come in a number of varieties and are used within concentrator supplies to hold tubes in place. These are also useful for minimizing the leakage that can occur, more effectively supplying user with oxygen. Adapters remain among the various oxygen products on the market, which also include oxygen connectors and chargers. Connectors are used to join different segments of oxygen tubing together while chargers are able to provide energy to oxygen concentrator batteries when they are unattached. These devices are meant to improve the effectiveness of oxygen equipment and can improve the experience for those who require them.
