Dupro 3/4 EMT Compression Connectors are used to secure and terminate a 3/4-inch (20mm) Electrical Metallic Tubing (EMT) conduit to an electrical box or enclosure.¹ These connectors create a robust, raintight, and often concrete-tight connection, making them suitable for use in both dry and damp environments within electrical wiring systems.² They typically feature a compression ring that tightens onto the EMT conduit at one end, and a threaded hub with a locknut at the other end for easy attachment to a knockout in an electrical box. Made from materials like zinc die-cast or galvanized steel, Dupro connectors ensure mechanical protection and electrical continuity for the conductors.
