NPTF Sight Glass, Size 1-1/2, Hastelloy C22, Borosilicate

Sight window with NPTF threads conforming to ASME B1.20.1.For use with all common hydraulic oils, refrigeration, water heaters, and compressed air applications. Note: The image of the objects behind the glass may be distorted as the glass is slightly concave. For perfect optical clarity choose sight glasses with glass filling the entire height of the housing, where both sides of the glass are flat.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.
