Model S Flange Circular Sight Glass

For applications that do not require significant temperature swings, a simple and economical gasket-sealed window works very well. Our Model S fills this niche, and it is available in ASME CL150 flange connection sizes (2" through 8"). Flanges are available in carbon steel and 316 stainless steel. Flanges are not wetted, so it is possible to use the carbon steel option even in applications that would be considered corrosive. These windows ship with Gylon 3500 sealing gaskets, which offer the corrosion resistance performance similar to that of PTFE along with superior seal retention.
