Thomas Betts Unf 505-TB Conduit Female Union 1-1/2 in Rigid Imc

Product Description

The THOMAS BETTS UNF 505-TB is a steel conduit female union designed for use with rigid metal conduit and intermediate metal conduit (IMC) systems. This straight, non-insulated fitting uses a threaded connection to join two conduit runs at a fixed point, allowing a technician to disconnect and reconnect the conduit without rotating either section. At a 1-1/2 inch trade size, it is suited for medium-to-large branch circuit and feeder conduit installations. Licensed electricians and electrical contractors install this fitting in both hazardous and non-hazardous locations where a removable conduit joint is required by layout or code.

This female union is rated for use in hazardous and non-hazardous locations, making it appropriate for industrial facilities, commercial buildings, and other environments where conduit runs must remain serviceable. The 1-1/2 inch trade size accommodates common feeder and branch circuit raceways in these settings. The threaded connection type suits rigid conduit and IMC systems where a secure, metal-to-metal joint is required. Electricians working on conduit runs that cannot be rotated for a standard coupling will find this fitting applicable to those conditions.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out all circuits in the conduit run before disassembling or installing any conduit fittings. Use appropriate pipe wrenches and thread sealant approved for electrical conduit connections. Verify that the conduit and fitting threads are clean and undamaged before assembly to ensure a secure, code-compliant joint.
