Glass Balls
Applications:
Because their polished surfaces provide an extremely good seal, glass balls are ideal for check valves in food processing, pharmaceutical, and photographic processing equipment. Black glass balls are used in flowmeters, slip and turn indicators, and other aircraft instrumentation. Fiber optics applications often rely on glass balls because they can be made optically clear.
Features:
Glass balls are dimensionally stable, resist corrosion and chemical absorption well, and can withstand temperatures up to 600°F. Glass balls vary in density depending on the type of glass they're made from, thus they're widely used in applications requiring a ball of a certain specific gravity.
