Standard 22mm tubing for CPAP and BiPAP. Ten foot lengths can affect pressures generated from your CPAP machine. Please be sure your machine can adapt to ten foot length or use only 6 or 8 foot tubing.
All Tubing is smooth bore designed. Smooth bores have no ridges inside the hose for air pressure to resist against. The supportive wire frame is located on the outside of the hose. This design provides consistent pressure delivery and ensures a quieter performing hose.
