Overview
An EMT Compression Connector 1-1/4" is a fitting used to connect 1-1/4-inch Electrical Metallic Tubing (EMT) conduit to electrical boxes, panels, or other conduit systems. EMT is a lightweight, thin-walled steel conduit used to protect electrical wiring, and the compression connector ensures a secure, grounded, and tight connection without the need for threading or welding. The 1-1/4" size corresponds to an EMT conduit with an outer diameter of approximately 1.375 inches.
Description
The EMT Compression Connector 1-1/4" employs a compression nut and ring system to secure the EMT conduit to the electrical box or other fittings. The compression mechanism ensures a tight and reliable connection that resists loosening due to vibration, mechanical stress, or other environmental factors. The connector is made from materials that provide high corrosion resistance and durability, making it suitable for both indoor and outdoor installations. It is ideal for systems that require a safe grounding path as part of the overall electrical system.
