Circular Sight Windows

Our sight glasses allow direct visual observation of processes within industrial pipes, tanks, and vessels. Most competing units consist of a piece of glass sandwiched between two metal flanges. By contrast, our sight windows are designed to circumvent the significant limitations of such designs, and provide the users with an easily maintained installation that offer large margins of safety. Custom safety sight glasses can be designed to meet your exact specifications.

The majority of our units are Factory Mutual approved. The following standard models are available for immediate ordering at (800) 624-9043 (click on any listing for a product description, engineering details, materials of construction, and unit image).
