The stiffener consists of two layers of high-strength braided steel wire, which makes the pipe strong and resistant to high pressure. Therefore, it has excellent performance under high pressure working environment. Pipe: high quality synthetic rubber, abrasion resistance, corrosion resistance, oil resistance. Reinforcement: Two layers of high strength braided steel wire make the pipe have excellent performance under high pressure working conditions. Cover: high quality synthetic rubber, abrasion resistance, corrosion resistance, cutting resistance, aging resistance, weather resistance, ozone resistance.
