Manufactured in 3.3 Borosilicate Glass, these level gauge glass tubes are used in several applications where a good chemical resistance and low thermal expansion coefficient are required. Outside Diameters go from 1/2” to 1-1/2”, and length of the tubes from 1” to 144”. Ends are cut with a special diamond equipment in order to assure sealing and avoid sharp edges.
ZIGHT BOROSILICATE TUBES are available in different wall thicknesses according to customer specifications, and both in Red Line and Transparent. The Red Line tube is treated with a special Paint (two White lines and one red line) which creates an optical effect that magnifies the level of the fluid, and allows a distant and quick inspection.
