Thomas Betts Uny 405-TB Conduit Male Union 1-1/4 in Rigid Imc

Product Description

The THOMAS BETTS UNY 405-TB is a steel conduit male union fitting designed for use with rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems. It features a threaded connection in a straight configuration and is sized for 1-1/4 inch trade size conduit. The fitting is non-insulated and rated for both hazardous and non-hazardous area applications. Electricians install this type of union to create a separable, field-removable joint between two fixed conduit runs where standard couplings cannot be rotated to thread onto the conduit.

This male union fitting is used in commercial and industrial electrical installations where rigid or IMC conduit must be joined at a fixed-position junction. Common install scenarios include panel feeds, motor branch circuits, and conduit runs through walls or enclosures where access for future disconnect and reconnect is required. The 1-1/4 inch trade size suits medium-capacity feeders and branch circuits found in both light commercial and heavy industrial environments.

Key Features

• Threaded connection type for secure, code-compliant assembly with rigid and IMC conduit
• Straight connector shape simplifies in-line union joints on fixed conduit runs
• Steel construction provides mechanical durability in demanding installation environments
• Non-insulated design suitable for standard conduit grounding continuity configurations
• Rated for hazardous and non-hazardous area applications
• 1-1/4 inch trade size accommodates common feeder and branch circuit conduit runs

Compatibility

Designed for use with 1-1/4 inch trade size rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems in hazardous and non-hazardous locations.

Installation Notes

Installation is performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits and lock out the panel before beginning conduit work in the area. Apply listed thread compound or thread tape to all threaded joints as appropriate for the application and environment. Ensure conduit grounding continuity is maintained through the union assembly per NEC requirements.
