Below is a list of Clear Plastic Tubing manufacturers from Germantown, Wisconsin. Clear plastic tubing products are hollow, transparent or semitransparent channels used to transport liquids, gasses and solids (though solids that are moved through tubes are usually granular or free-flowing). There are many applications for which the use of clear tubing might be required. Many banks feature drive-through services, and the transportation of money, checks and receipts between vehicles and indoor bank tellers requires the use of vacuum tubes and a mobile container.
