When diving, the tubes used are essential for survival. Without a free tube on the regulator you cannot breathe under water. Your pressure gauge also only works if the tube is free. However, tubes are exposed to important strain under water. Therefore, a lot of divers use so-called bending protectors, to protect tubes from breaking.
How do I use bending protectors?
In principle, these are tubes themselves made from a relatively thick, minimally flexible material. You simply slide them over the end of the tube that you wish to protect. What is important to protect is the transition between the rubber tube and the valve, which is mostly made of metal. Then here the burden on the tube is the greatest.
