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

The assembly is sealed using D-ring or O-ring seals, selected according to the process requirements, made from materials such as PTFE (Teflon\u00ae), NBR, silicone, EPDM or FKM. <\/p>\n

\n

For greater protection against aggressive chemicals or caustic solutions, borosilicate glass can be coated with FEP or Halar\u00ae.<\/p>\n

Like other circular product sight glasses<\/a>, the 390V sight glass can be fitted with LED lighting on request.<\/p>\n
