Sanitary Tubular Sight Glass

Tubular Glass are manufactured in 3.3 Borosilicate Glass and used in several applications where a good chemical resistance and low thermal expansion coefficient are required. These 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. Control Specialties is proud to offer these Sight Glass Indicators.
