Rectangular Sight Glasses

Obround and rectangular sight windows with a weld-on base pad. In typical applications the base flange is welded to the process vessel, and the rest of the sight window components mount into that base flange. Glass is sandwiched between a sealing gasket and a cushion gasket. Cover flange is bolted to the base flange holding the assembly together. Gaskets, mounting hardware and the glass can be replaced during scheduled service intervals or as needed.. Choose from obround or rectangular sight glasses.

Rectangular and obround sightglass fittings are common for viewing inside pipelines, pressure vessels, liquid tanks. Primarily used for liquid level observation.
