Pressure-Rated Borosilicate Glass Disc
Manufacturer part: 8475K65
Commonly used as sight glass. Also called Pyrex and Schott glass, borosilicate glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.Tempered glass is stronger than annealed glass.
