Borosilicate glass 3.3<\/strong>, highly chemically resistant, Type 650 provides full 360\u00b0 visibility<\/strong> of the flow inside the pipeline.
The glass used features high thermal and chemical resistance<\/strong>, making it ideal for demanding media<\/strong> and rigorous industrial applications.<\/p>\n

To ensure a reliable and durable seal<\/strong>, the following sealing materials are used:<\/p>\n

    \n
  • NBR<\/strong><\/li>\n
  • EPDM<\/strong>
    (Other materials available upon request)<\/em><\/li>\n<\/ul>\n

    The design incorporates stud bolts with flange stops<\/strong>, preventing incorrect assembly and increasing breakage resistance<\/strong>.
    The defined gasket pre-compression<\/strong> on the glass cylinder ensures a uniform seal<\/strong>, while self-locking nuts<\/strong> maintain constant pressure<\/strong> and maximum operational safety<\/strong>.<\/p>\n

    To protect the glass tube, Type 650<\/strong> is supplied as standard with an impact protection cover<\/strong>, available in polycarbonate<\/strong> or perforated metal sheet<\/strong>.
    This protection prevents mechanical damage and significantly increases the durability of the sight glass<\/strong> during operation.<\/p>\n
