Polycarbonate Level Tube
Polycarbonate is a group of thermoplastics that are easy to work with, mold and thermoform, and are widely used in modern manufacturing. The name “polycarbonate” is based on the fact that they are polymers that have functional groups joined by carbonate groups in a long molecular chain.

Polycarbonate tubes used in level gauges combine durability with optical clarity, making them an ideal choice for monitoring fluid levels in a variety of settings. Polycarbonate is a tough thermoplastic that is easy to work with at high temperatures and is widely used in modern manufacturing due to its excellent characteristics and chemical resistance. These products are primarily used in fluid level monitoring equipment where breakage is a possibility due to vibration or impact.
Polycarbonate is FDA-approved and widely used in water treatment, food and beverage processing, and chemical and pharmaceutical industries. As mentioned earlier, polycarbonate level gauge glass is extremely versatile in terms of chemical resistance; ensure that the chemicals in your application are compatible with this material. If you need assistance selecting the best level gauge glass for your project, contact a Douglass representative.
