Eaton 667RT Raintight Steel EMT Compression Coupling

Eaton Crouse-Hinds 667RT Raintight Steel EMT Compression Coupling is a weather-resistant fitting designed to join two 3" EMT conduit runs using a compression connection. Crafted in steel, this 667RT coupling provides a robust, durable joint suitable for outdoor or damp environments where a raintight seal is required. The 3" EMT sizing indicates it’s made for 3-inch conduit, making it compatible with standard steel EMT tubing and other components in Eaton’s Crouse-Hinds line. As a compression-type coupling, it is engineered to secure conduit ends and maintain enclosure integrity across runs in commercial and industrial electrical installations. By delivering a solid, metal-to-metal conduit join, the 667RT helps resist environmental exposure that can compromise connections over time, supporting long service life in raintight applications. It is compatible with other Crouse-Hinds and Eaton fittings designed for 3" EMT to ensure a consistent, code-ready installation.
