Toughened borosilicate round window. Edges are chamfered, cylindrical surface is ground and polished. Flat faces have optical finish 40-60 S-D. This window is designed to fit Lumiglas sight glass fittings meeting DIN 28120 with weld-on pads, and also DIN 11851 sight glasses with a screwed on cover flange.

For safety compliance in accordance with DIN 7080 the window must be replaced every time a sight glass assembly is disassembled during scheduled or unplanned maintenance. Once the sight glass disc is removed it should be discarded and not reused, especially on vessels under pressure or vacuum. The glass and the gaskets should be replaced during every time the assembly is taken apart.

Maximum operating pressure can be achieved only when the window is properly installed and tightened with the torque setting and criss-cross tightening pattern recommended for the sight glass assembly. Max operating temperature is 280 degrees C, no lower temperature limit. The window provides distortion-free viewing inside process chambers, mixers, pipelines, silos, food processing vessels. Not recommended for prolonged use with demineralized water.
