Tubular sight glass type 650 with connections according to DIN 11851
Tubular sight glass fitting with connections according to DIN 11851
The ACI tubular sight glass with connections to DIN 11851 Type 650 is based on our proven type 620, but is intended for installation with milk tube fittings in various variants.
As with the Type 650 Sight Glass, the core is a glass tube made of industry-proven borosilicate glass 3.3, which is enclosed by two solid stainless steel flanges.
For sealing, we use NBR, EPDM or PTFE as for our tubular sight glass type 650. Other materials are also available on request. Like our Type 620, the necessary contact force is applied to Type 650 by threaded rods, which simultaneously protect the sight glass from compression and bending. The sight glass also comes with our impact protection jacket on request. This reliably protects the sensitive glass tube from falling tools or other hard objects and thus ensures a longer service life for your fitting.
The Type 650, like all our tubular sight glasses, is subjected to a pressure test before delivery in order to ensure that the sight glass in your system is guaranteed to withstand the operating pressure.
