ASME Sight Glasses

Sight windows conforming to the standard ASME B16.5 flange sizes are a good choice for pressure tanks, vacuum chambers, ovens for baking out parts in semiconductor and clean room applications. The housing is flanged, conforming to the ASME B16.5 standard. These sight glass are engineered and tested to meet rigorous safety standards.

ASME B16.5 - Flanged Sight Glass, Borosilicate Windows

Sight window for corrosion resistant applications. Flange conforms to the standard ASME B16.5 geometry. Suitable configuration for flue gas scrubber systems, cooling towers, incinerators, geothermal wells, deep/shallow sea water applications, biofuels, food, and pharmaceutical processing equipment. Requires parallel mounting flat face and full gasket. Fusing glass to metal creates a hermetically sealed single-piece part. The advantage of this construction is high strength of the glass, which ensures safety of operation, even during cycling operating temperatures common with equipment starts and stops. The part is easy to install, and has a long working life without maintenance.
