This sight glass lens is suitable for use with any 3" tri-clamp ferrule with a 3" clamp and gasket. Made of Polyphenylsulfone (PPSU) which offers the clarity of transparency of glass with a much higher shatter and heat resistance.
This is a direct replacement part for the Pro Sight Glass Distillation Lid.
PPSU is an excellent choice for components that are exposed to high temperatures (up to 392°F) and corrosive media due to its exceptional chemical resistance, as well as being extremely impact resistant, and with the added benefit of being see-through.
