Precautions to use the brake system of a car
When we buy PVC plastic hoses in stores, many consumers will worry about what kind of hose is considered to be superior. A good plastic hose can be used for 3-5 years, while a low-quality one will have oil, hardness, discoloration and other phenomena in less than 1 year. Then how to choose a high quality garden hose?
First look
First, look at the appearance of the garden hose, judging by the color, wall thickness, uniformity of the network, etc. The thicker the wall, the denser and more uniform the network, which means that the hose will not be too bad. Secondly, see if it is produced by a regular manufacturer. All regular manufacturers will print the manufacturer. Some important product parameter information, and have a traceability code.
Second touch
Surface smoothness, touch the surface with your hand to see if it is smooth. Bend the tube to see if it will rebound and how fast it rebounds. The faster the rebound speed, the better its elasticity and the less likely it is to deform.
Third smell
Does it have some pungent odor. If you can clearly smell a pungent odor, it means that the PVC plastic hose is not an environmentally friendly material.
