The plastic protective sleeve is a new product that replaces the traditional metal protective spring for hose protection. Plastic protective sleeves are generally made of nylon or polypropylene. The plastic protective sleeve has good wear resistance, anti-aging and anti-corrosion properties corresponding to the traditional metal protective spring products; it can more effectively protect the outer surface of the hose against aging and friction. Compared with hose spring protection products and other sheath products, the plastic protective cover has better convenience, environmental protection and energy saving effects. The inner surface of the plastic protective sleeve is generally flat, and the outer surface is divided into flat and curved surfaces.
