The standard version is equipped with 1.4571 (316Ti) stainless steel flanges,<\/strong> a material known for its excellent corrosion resistance<\/strong> and durability in industrial applications.
For less demanding applications, a variant with P265GH<\/strong> flanges is available.
Additionally, special materials such as Hastelloy\u00ae, duplex steels<\/strong>, or other high-performance alloys can be supplied upon request.<\/p>\n

The glass tube<\/strong> is made of industrially tested borosilicate glass 3.3<\/strong>, in accordance with DIN ISO 3585<\/strong>. It stands out for its high thermal and chemical resistance<\/strong> and excellent optical properties<\/strong>. <\/p>\n

Sealing is achieved with individually selectable flat gaskets<\/strong> from a wide range of materials \u2013 from classic fibrous materials<\/strong> to high-quality special materials such as PTFE (Teflon\u00ae), NBR, novaphit\u00ae MST-XP, or KlingerSil\u00ae C4400<\/strong>.
This allows the gasket to be ideally adapted to the medium, temperature, and pressure<\/strong>.<\/p>\n

For nominal diameters up to DN 50<\/strong>, the Type 620 tubular sight glass<\/strong> is designed for operating pressures up to 16 barg<\/strong>.<\/p>\n

Thanks to the precise coordination of the flange, gasket, and glass<\/strong>, the assembly is virtually dead-space-free<\/strong>, making it suitable for hygienically demanding processes<\/strong>.<\/p>\n

For areas with increased mechanical risks<\/strong> \u2013 for example, when installed under walkways \u2013 optional impact protection covers<\/strong> are recommended, which, by protecting the glass tube from falling objects<\/strong>, minimize the risk of failure or unplanned damage.<\/p>\n
