What is Sight Glass?

a sight glass is a transparent glass tube or window installed in a tank or boiler system that allows an observer to view what is happening inside the container, ensuring optimal quality and safety. Sight glasses can also serve a number of functions aside from basic viewing, but this is the most common use.

While “sight glass” is a general, overarching term, there are also several more specific terms that are used to refer to different types of sight glasses. Some of the most common types of sight glasses are outlined below.
