The Model S Flange sight glass combines the lowest cost on the market with the ease of installation and handling associated with our premium models.
There are many, less challenging applications that do not require the enhanced sealing performance or in-situ maintenance features of our premium sight glasses. For these applications, the Model S offers industry leading cost-effectiveness along with ease of installation that our premium models offer. The glass and flange assembly is bonded into a single piece so that a single technician can install the unit without having to touch or center the glass window. Sealing and maintenance characteristics are similar to other vendors' leading products. These units mount to standard ANSI B 16.5 (2" to 8") flanges. They are rated for service at up to 450F (232 C) and at 150 or 300 PSI ratings.
