1. When purchasing a pvc corrugated hose, the first is to check its appearance. A good pvc corrugated hose has a smooth appearance, no impurities and no air bubbles.
You can also have a try. Touch the surface of the pvc corrugated hose with your hand to see if it is smooth and then bend the hose to see if it is easy to bend. Good quality product is easy to bend and can recover easily.
2. When purchasing a pvc corrugated hose, the second thing is to drop the hose hard on the ground to see if it is easy to crack and then step on it with your feet to see if it is easy to return to its original state. If the hose is not prone to crack and is easy to return to its original shape, it is of good quality.
3. When purchasing a pvc corrugated hose, use a lighter to burn it at a certain distance below the hose again to see if it is easy to blacken or melt. If the pvc corrugated hose is not easy to be blackened or melted, its quality is good.
