Short description - Screwed Sight Glass DIN 11851 /EN 10357


The ACI screw-on sight glass Type 3227 is built based on EN 10357 (previously DIN 11851) specifically for food processing, medical applications and other industries with high hygiene requirements.

The base flange of Type 327 is welded onto an open pipe end according to DIN 11850 or EN 10357 and forms a strong, leak-proof connection to the main installation. The borosilicate disc according to DIN 7080 is sealed on the process side using a special ring seal designed for dairy connections. This seal is available made from PTFE, NBR or FKM. A threaded cover nut provides the necessary force.

Replacing parts is easily possible at any time with minimal downtime and with no need for special tools. Our sales team will assist you in case of problems.
