Welding Hose 1. Oxygen Hose / Acetylene Hose 2. ISO 9001 Certifacate 3.Tube: EPDM/SBR blended, black and smooth Characteristics:1. Tenacity: The products are made by polymerizing polyester terylene by and intwining terylene in the mesosphere of the hose, the products are produced. So the cracking of products is very high.2.           Burliness: PVC and Terylene are affixed by special engineering technology, avoiding abruption and stratification.3.           Permanence: The stuff is chosen strictly and is processed with precise filter net under consummate quality control system, leading to quality products with long life-span.4.           Pliability: The products are made by polymerizing terylene and mixing PVC at the best proportion, so the products are not only smooth but also flexible.
