Armstrong CD-42 NSNBC01 is a model in Armstrong International's CD-40/CD-60 series of controlled-disc steam traps, engineered to remove condensate from steam lines while minimizing steam loss. The CD-42 variant in this family supports pipe connections in 3/8, 1/2, 3/4, and 1 inch sizes, providing installation flexibility across different system configurations. An optional integral strainer is available to guard against debris and help maintain reliable trap performance. Used in heating and process applications, CD-42 traps help protect equipment and improve overall steam-system efficiency, with exact dimensions and weights varying by connection size.
