Product Details

Round sight glass, also called round gauge glass and sight glass disc, commonly uses the material of soda-lime glass, borosilicate glass, aluminosilicate glass and quartz glass. We suggest different material according to environmental conditions, such as temperature, pressure, acid and alkali.

Soda-lime glass working temperature is up to **0 °C, but it is the most inexpensive material. Borosilicate glass is particularly used in aggressive environment, such as acid and alkali. The working temperature is up to **0 °C. Aluminosilicate glass can resist acid and alkali better than borosilicate glass and the working temperature can reach **0 °C. Quartz glass is the best material, whose working temperature can reach ***0 °C.
