Duraport Raised Face Flange Fused Sight Glass

Our DuraPort Raised Face Flange Sight Glass merges the strength of steel with the visual clarity of glass.

These self-contained units are created by fusing a glass lens inside of a metal ring. The Raised Face units are designed to bolt between a new or existing flange connection and a cover flange, and require no maintenance. These units are also available with an ANSI weld pad which can be machined to fit the radius of the vessel for a complete weld-on sight glass package. Standard units are for ANSI flanges but other types (such as DIN) are available upon request.
