Clamping Connection Sight Glass Type 328

With clamp connection according to DIN 32676

Clamping connection sight glass type 328

The ACI clamp connection sight glass type 328 is another variant of our tank sight glasses. The sight glass fitting type 328 is mounted directly to a clamping socket flange according to DIN 32676. Sealing against the flange is achieved by means of a sealing ring. A clamp is used to tighten the sight glass to a socket and an internal gasket. This connection is therefore quick to assemble and disassemble. This allows easy cleaning of all components.

The clamp sight glass type 328 is available in nominal sizes from DN 10 to DN 300, ISO 8 to 300 and even in ASME BPE from 1/2" to 12".

We offer the required sealing rings in materials such as PTFE (Teflon®), NBR, EPDM, FKM and silicone.

Just talk to our consultants to determine the ideal combination for your application!
