KSW Series Threaded Sight Windows

KSW Series Threaded Sight Windows


KSW Threaded Sight Windows are a low cost solution for viewing liquids.  The hexagon head body with a male NPT mounting connection allows for easy installation.  Clear glass lens is hermetically sealed and fused to the metal body to ensure leak-proof service and eliminate concerns typically found with traditional gasket type sight window assemblies.  The optical clarity of the glass lens transmits an accurate view of the liquid being viewed in the window.  Lens is flush with the front face of the body which allows for easy cleaning and prohibits build up of dirt and debris normally associated with sight windows having a recessed lens.  KENCO KSW sight windows reliably meet and exceed the requirements of most applications.
