Feature: 1. Wear‑resistant and slip‑resistant, bass and high speed, the surface of the drag chain is smoothly and firm, reducing the resistance and friction with the air pipe. 2. The material is made of nylon 66 that is resistant to low temperature ‑25℃ and high temperature 100℃. 3. Can be disassembled and combined in any length, 1m/0.7m can meet work needs. 4. Selected fine materials are accurate processed, and the product life cycle is greatly extended. 5. Very low working noise, making the working environment quieter and less noise.
