Salter Labs Oxygen Tubing 4.2 meter length. This replaces the popular 4.5m tubing length. The Oxygen Tubing is very useful for attaching your oxygen mask or nasal cannulas to your main oxygen supply. The use of a swivel connector will provide you with even more flexibility for connecting multiple lengths together.
The 4.2m oxygen tubing can also be helpful if you are using a portable concentrator whilst in the bathroom, where the longer tubing allows you the benefit of supplementary oxygen, but protects the Oxygen concentrator from exposure to high moisture environments.
