Durable tempered glass is used for the windows, which are fixed firmly in place by stainless steel frames. The compact size of the Double Window Sight Glass also makes installation in small locations simple. This sight glass is a trusted method for keeping track of fluid levels, finding leaks, and guaranteeing that industrial systems are running properly.
