Crouse-Hinds 661S Steel Compression EMT Coupling is a steel conduit connector designed for 3/4-inch EMT conduit. This compression-type fitting joins two lengths of electrical metallic tubing, providing a secure, durable connection in standard EMT installations. The 661S designation identifies the 3/4 in conduit size, ensuring precise compatibility with common EMT systems. Constructed from steel, this coupling offers robust mechanical strength for everyday electrical conduit runs. It’s sized specifically for 3/4-inch EMT, making it a straightforward, non-threaded way to extend or bridge sections of conduit in metal conduit installations.
