Dupro 1/2 EMT Compression Connectors are used to secure and terminate a 1/2-inch (15mm) Electrical Metallic Tubing (EMT) conduit to an electrical box or enclosure. These connectors provide a rigid, raintight, and often concrete-tight connection, suitable for both dry and damp locations in electrical installations.¹ They typically feature a compression-style mechanism that tightens around the EMT conduit on one end, and a male threaded hub with a locknut on the other end for attachment to the knockout of a box. Dupro connectors are commonly made from zinc die-cast or galvanized steel, ensuring durability and electrical continuity for the protection of electrical wires.
