Thomas Betts Unf 305-TB Conduit Female Union 1 Inch Rigid Imc

Product Description

The THOMAS BETTS UNF 305-TB is a steel conduit female union designed for use with rigid metal conduit and intermediate metal conduit (IMC) systems. This straight, threaded connector joins two sections of conduit end-to-end, maintaining a secure and continuous raceway without requiring rotation of the conduit itself. Rated for both hazardous and non-hazardous locations, it suits a wide range of commercial and industrial wiring applications. At 0.63 pounds, it is a compact, non-insulated fitting suited for licensed electricians working in demanding environments.

This female union is sized for 1-inch trade size conduit and is intended for use in electrical installations where rigid or IMC conduit must be joined inline. Typical install scenarios include industrial plant wiring, commercial construction, and service work where conduit runs cannot be easily rotated to complete a threaded connection. Its suitability for hazardous locations makes it a practical choice in environments classified under NEC Article 500 requirements.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits before beginning any conduit work. Ensure threads are clean and fully engaged before tightening, and apply appropriate thread sealant or conduit thread compound as required by the installation environment. In hazardous locations, verify that the complete conduit assembly meets the classification requirements for the area before energizing.
