Dupro 1 1/2 EMT Compression Type Couplings are designed to connect two lengths of 1 1/2-inch (40mm) Electrical Metallic Tubing (EMT) conduit. These couplings provide a secure, raintight, and often concrete-tight connection, making them suitable for use in both wet and dry indoor locations. They are typically constructed from materials like zinc die-cast or galvanized steel, offering durability and corrosion resistance for electrical raceway installations.¹ The compression design ensures a strong mechanical bond and electrical continuity between the EMT conduits, protecting the enclosed electrical wires.
