This elbow connects the CPAP machine and the standard 22mm or 15mm CPAP tubing. It changes airflow directions by 90 degrees. Compatible to any CPAP machine using plastic tubing (heated tubing is NOT compatible).
Fits perfectly and very well made. This was my first order from Respshop and it couldnt have been any better. Absolute perfect all-around transaction. Highly recommended!
Fits perfectly and does exactly what it's supposed to do.
