The ResOne HBA‑100 Humidifier Bottle Adapter Tubing provides a secure, reliable way to connect a standard oxygen humidifier bottle to an oxygen source. This 12‑inch adapter features a 9/16‑18 UNF threaded connector on one end for attaching to the top of most humidifier bottles, and a push‑on tubing end on the other for connecting to a compatible oxygen outlet. The flexible tubing installs quickly without tools—simply thread the connector onto the humidifier bottle and push the opposite end onto the oxygen source. Built with durable, smooth‑edge materials, the adapter resists kinking and maintains consistent airflow during everyday use. Ideal for replacing worn adapters or keeping a spare on hand, the HBA‑100 adds convenience and reliability to any standard oxygen humidifier bottle setup.
