3 · Typical Applications
Water dispensers and purifiers, coffee machines, steam cleaners and small appliances — anywhere a clear, odorless food-contact fluid path is required. Medical and laboratory equipment: ventilators, oxygen concentrators, dental equipment, beauty devices. The smooth, inert silicone surface keeps the tubing suitable for long-term contact with drinking water and sensitive fluids.
