Spiral protective sleeve arc type has the following characteristics and advantages:

• Easy installation: No complicated operations and tools are required.

• Good wear resistance: It can effectively reduce the wear of internal products caused by external friction.

• Anti-aging, strong corrosion resistance: can protect internal products in various environments.

• Enhanced performance: Enhance the anti-static and anti-ultraviolet properties of internal products such as hydraulic hoses, wires, cables, etc.

• Safety protection: protect internal products in harsh environments.

• Extended life: After installation, the service life of internal products can be extended.

• Beauty enhancement: make the hydraulic hose, wire, cable and other products more clean and beautiful.

The arc type of spiral protective sleeve has been widely used in excavators, loaders, road rollers, pavers, forklifts, cranes, dump trucks and other construction machinery and injection molding machine equipment, mainly installed in the external of hydraulic hose, wire, cable and other products.

When using the arc spiral protective sleeve, the manual installation method is as follows: firstly, turn the middle part of the rubber hose (wire, cable) around the middle part of the spiral protective sleeve, and turn the end of the rubber hose (wire, cable) from the wound middle part; after the end of the rubber hose (wire, cable) is wound and positioned at the joint of the rubber hose (wire, cable), turn the spiral protective sleeve reversely and loosen, can be random...
