Bosco Oxygen Tubing 4.5 meter length. Useful for attaching your oxygen mask or nasal canulars to your main oxygen tubing. The use of a swivel connector will provide you with even more flexibility.
The 4.5m 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 portable concentrator from moisture.
