Manufactured in Soda Lime Glass, these sight glasses are used in several applications where the cost-reduction is important, and the glass will not be in contact with food, drugs, chemicals, or temperatures above 300 F.

Special dimensions of glasses are available upon request, where the minimum diameter is 10mm, and the maximum diameter is 350mm. The thickness can be manufactured to a minimum of 3mm and a maximum of 25mm. Do not hesitate to contact us for recommendations as to which sight glass fits your application the best.

MANUFACTURED IN ACCORDANCE TO DIN 7080
In order to achieve the standardization of this type of type of sigh glasses in all the different industries, the German regulatory institute, DIN for its acronym in German, designed standard parameters for the manufacture of this type of glass.

The main issues this norm regulates is the pressure resistance in terms of the total diameter of the glass, the observable diameter of the glass, and the glass thickness. It also dictates permissible imperfections in the glass, chemical attack, markings, and dimensional tolerances.
