The Type 390 circular sight glasses are manufactured from high-quality 1.4571 (316Ti) stainless steel, a material trusted by our customers. The glass used is the industry-standard borosilicate glass, in accordance with DIN 7080 (or to customer specifications). <\/p>\n<\/div>\n

The assembly is sealed using flat gaskets, selected in accordance with process requirements from a wide range of materials. In addition to traditional fibre gaskets, advanced options are available, such as PTFE (Teflon\u00ae), NBR, novaphit\u00ae MST-XP, KlingerSil\u00ae C4400, and other leading brands. <\/p>\n

\n

Where the maximum operating temperature of DIN 7080 borosilicate glass is insufficient, or where process conditions require additional protection, a specially sized mica protective disc can be fitted to this model, offering greater resistance to temperature and steam. For environments involving aggressive chemicals or caustic solutions, FEP or Halar\u00ae coatings can be applied to enhance durability. <\/p>\n

Like other circular product sight glasses<\/a>, the 390 sight glass can be fitted, on request, with an SGW-type wiper and lighting systems.<\/p>\n
