The spiral sleeve was introduced into China in about 2002. It has been widely used in excavators,loaderRoller, road roller,paver,Forklift truck, crane,Dump truckConstruction machinery and injection molding machine equipment. Mainly installed in the hydraulic hose, wire, cable and other products outside. Its function is to enhance the hydraulic hose, wire, cable and other internal products wear resistance, anti-static and anti-UV performance, in various adverse environments on hydraulic hose and other internal products play a role in safety protection.Hydraulic hoseScrew protector can not only improve the beauty, but also extend the life of the internal products by more than 3 years. Compared with the traditional metal spring product, the rubber hose is easy to install and has better wear resistance. Strong resistance to aging and corrosion; More powerful to hydraulic hose, wire, cable and other products on the surface of anti-aging and anti-friction protection; With more excellent, more convenient, more environmental protection and energy-saving effect.

The spiral protective sleeve is spiral, with good elasticity and tensile force, which can restrain the internal products such as hydraulic hose, wire and cable. Domestic use of raw materials for polypropylene (PP), polyethylene (PE) or nylon (PA), so that the product has a good wear resistance. In addition, the screw protector also has good high and low temperature resistance, oil resistance, uv resistance, antistatic, impact resistance, tensile resistance and other properties.
