Pureflex® is designed for use where water main service is disrupted and temporary bypass hoses are used to supply drinking water to homes and businesses. The tube compound meets the toughest standards for potable water applications and will not transfer an odor or taste to the water. In addition, the tube in G1031 is less porous than rubber, and therefore is easier to flush and clean after use and prior to re-use. The heavy-duty construction limits kinking in hot weather and provides extra resistance to external wear and abuse.
