Threaded Sight Windows

Available with brass or stainless steel retaining rings, these sight windows can be used anywhere that a 1/4" to 3" piping "T" or a female NPT exists.

The two available Threaded Sight Windows are rated at ANSI 150# and 300# using tempered borosilicate glass. There are no dimensional differences between the 150# and 300# models.

The Threaded Sight Window is similar in design to the Threaded Window Sight Flow Indicator. The outer retaining ring compresses the glass between the gasket and cushion.

Spanner wrenches for window removal are available. The spanner wrenches have a 1/4" or 1/2" drive socket for torque wrench. All Threaded Sight Windows are machined from hex barstock.
