MS Frame Sight Glass

MS Frame Sight Glass is a heavy-duty inline visual inspection device designed to monitor liquid flow in non-transparent industrial pipelines . It provides 360-degree clear visibility  and is suitable for both horizontal and vertical installations .

The assembly is engineered to protect the borosilicate glass from mechanical stress while maintaining excellent chemical and thermal resistance .

Construction & Design

The MS Frame Sight Glass consists of the following precision-engineered components:

• Borosilicate Glass 3.3 Pipe Section
• High thermal shock resistance
• Excellent chemical compatibility
