Restore airflow performance and flexibility with the ResMed AirFit F40 Elbow. This component connects your F40 mask to the CPAP tubing while providing a swivel interface that reduces drag and allows natural movement during sleep. Over time, wear or loosening at the elbow can lead to leaks, noise, or restricted airflow—affecting comfort and therapy effectiveness.
 
Replacing the elbow helps maintain a secure connection, smoother airflow, and a more comfortable CPAP experience.
