Threaded sight glass fitting type 327 - similar to DIN 11851 / EN 10357

Threaded sight glass type 327 - for areas with high hygiene requirements similar to DIN 11851 /EN 10357


The ACI threaded sight glass based on EN 10357 (old DIN 11851) is specially designed for use in the food industry, medicine and other areas with high hygiene requirements.

The base flange of the sight glass is welded to an open pipe socket according to DIN 11850 or EN 10357 and thus forms a resilient and tight connection with the rest of the system. On the media side, the borosilicate glass disc, which complies with the DIN 7080 standard, is sealed by a gasket ring made of NBR, FKM (Viton) or PTFE, which is specially shaped for milk pipe screw connections. A groove nut provides the necessary support.

Individual parts can be replaced at any time with very little effort and without special tools.

Our sales team will be happy to advise you should any difficulties arise.
