Type 338 - PN16



The ACI container sight glass Type 338 is a robust series of oval container sight glasses with working pressure up to 16 bar. Due to the use of borosilicate transparent sight glass panels according to the standard industry norm DIN 7081, it is possible to use it in working temperature up to 243°C. The “transparent” type enables the use of protective layers such as mica, KEL-F, PRFE or FEP to protect the glass surface from chemical and thermal influences.

Sealing is provided, like for most of our sight glass fittings, by high-quality flat seals such as KlingerSIL C4400, Graphite or chemically highly-resistant PTFE. Durable soft seals such as silicon, EPDM or NBR can also be installed in your fitting by the factory.

As flange material, you can choose from our whole catalogue of high-quality types of steel and stainless steel, such as 1.4571, 1.4404 or P265GH. 

If it is necessary to replace the glass or seal, our competent team of technical and sales consultants will help to provide a solution as quickly as possible.
