Medline HCS 455010 Crush Resistant Oxygen Tubing 50' (15.2M) CLEAR
The 50' Disposable Oxygen Tubing is crush-resistant, soft and memory-free allowing for a greater comfort for you as well as being easily managed during use. The tubing is a excellent choice to be used with a stationary oxygen concentrator in the home.
If you are looking for oxygen tubing for a portable unit, the shorter 25' tubing would be recommended as the 50' tubing may be too long to carry and may become a tripping hazard.
