Wiper Assembly


The Wiper Assembly satisifies the need to wipe the lens clean on the process side of the sight glass. It is designed to fit with mating gaskets between a standard flange (ANSI B16.5) and most PresSure Products sight glass flange units (ANSI B16.5). The outside diameter of this Wiper is machined to fit inside of the flange bolts, thereby centering the Wiper. The Wiper can also be built as an internal component of most PresSure Products sight glass weld units. Sizes for non-ANSI flanges are available upon request.
