If the PET hose and PVC hose, here is transparent hose classes.
PET tube forming is divided into two steps, first namely injection molding and blow molding, so every PET the lower end of the hose has a mouth, take a look at to know.
PVC is made of blow molding, injection is required to make, so there is no mouth.
So pick up a hose have note mouth is a PET, not PVC.
If is mass production, the total tube steam steaming, after high temperature steam of PVC will become opaque, PET or transparent, sorting up both recognisable and save trouble, and after steamed label tape will automatically come unglued, with handle gently tear is removed.
Hose is bad to recognize, can only use the boiled or steamed
