Protection, ready visibility, and ease of access are three conditions desired of sluice gate, valve stem, slide gate, and weir gate protectors. Before transparent butyrate covers, these were problems. The traditional protection employed galvanized steel with its drawbacks of poor visibility, unknown position of the gate, and weight.
Decades ago, Rodney Hunt Company, Orange MA and Waterman Industries, Inc., Exeter, CA used butyrate tubing to protect their stems from weather.
Tough, transparent, weather resistant plastics tubing protects valve stems and provides ready visibility. Busada 200® transparent tubing is specified because of its superior properties. Weatherability and transparency is maintained for extended service life as the material contains inhibitors to protect against ultraviolet degradation. In addition, the thick, tough walls provide mechanical protection to the valve stems.
Available in stock, there is a tubing to protect virtually any size stem.
