KL25973 2 Inch TC PPSU Sight Glass / End PlateThis sight glass is suitable for use with any 2 Inch Tri-Clover ferrule with a 2 Inch Tri-Clover Flat Seal and 2 Inch Tri-Clover Clamp.This sight glass is also a replacement for the sight glass provided in the BrewZilla Distillation lid with sight glass.This 2 Inch Tri-Clover sight glass is made of Polyphenylsulfone (PPSU) which offers the clarity of transparency of glass with a much higher shatter and heat resistancePPSU is an excellent choice for components that are exposed to high temperatures (up to 200°C) and corrosive media due to its exceptional chemical resistance. As well as being extremely impact resistant. ​ ​We have decided to use this type of plastic because it also has superior thermal and mechanical properties with the added benefit of being transparent. This will allow us to injection mold intricate parts that would have been near impossible to do in stainless steel or lab-grade glass. Because this is a very unique type of plastic, it comes at a much higher cost per kg than other industrial plastics. So much so that it costs more than stainless steel!
