First: Look at the color. When choosing the material of hose protective sleeve, we should choose the smooth and colorful spiral protective sleeve as far as possible. The general material of this kind of hose protective sleeve is relatively better.
Second: Look at elasticity and softness. Why does polyethylene replace the spring to make rubber hose sheath? Formally because it has good resilience and is easy to install, it is soft because sometimes rubber hose or tubing wire and cable are not on the same level, so the sheath needs to be bent a little.
Finally, smell. Generally speaking, rubber hose sheaths with odor are polluting the atmosphere or the environment, and sometimes even harmful to our health. Therefore, when choosing rubber hose sheaths, we should try our best to choose odorless, environmentally friendly and indoor use.
