How to distinguish the quality of PVC hose

The goods on the market are mixed, so how do we distinguish the quality of PVC plastic hoses?

First, distinguish from the smell. The smell of high-quality PVC hoses is a normal light plastic smell, while the smell of low-quality PVC hoses is very pungent, and the smell will not fade away over time.

Second, distinguish from flexibility. Generally speaking, the higher the flexibility, the better the quality of products that are suitable for the same region. The lower the flexibility, the worse the product quality.

Third, distinguish from colors. The high-quality PVC hose looks shiny and transparent, and the pipe wall is free of impurities. The poor PVC hose has poor brightness, opacity and even impurities.

Fourth, from the wall thickness. The wall thickness of high-quality PVC hose should be uniform. The inferior PVC hose is likely to be thick at one side and thin at the same time, which will seriously affect the service life of the product.

Fifth, from the view of steel wire or fiber density. High quality PVC hose has high steel wire or fiber density and high pressure bearing. The poor PVC hose steel wire or fiber has low density and low pressure.

Finally, from the position of the wire or fiber. High quality PVC hose steel wire or fiber is located in the center of the pipe wall. The position of inferior PVC hose, steel wire or fiber is not stable enough, with large deviation.
