They feature an integrated spring steel wire, wall thicknesses of 0.35 mm, are made out of PVC coated fabric, and are flame-retardant (UL94-HB). They are mostly used for welding gas extraction and air ventilation technologies. These hoses are lightweight, reinforced, with high resistance to alkalis, acids, chemicals, or UV and ozone.
