For certain applications, it is an advantage to have a flexible plastic or rubber outer cover extruded on to the hose. The cover provides protection for the braid, as well as being easy to clean, and can be printed with a continuous text line.
Covered hose is, however, only available to special order, so price and availability are very dependent upon quantities required.
