Appleton UNY75-50NR Male Union 3/4 X 1/2 Inch Conduit Fitting

Product Description

The APPLETON UNY75-50NR is a male union conduit fitting designed to join two sections of rigid or IMC conduit in electrical raceway systems. It provides a threaded, removable connection point that allows installers to disconnect conduit runs without cutting or disassembling the surrounding system. The fitting transitions between a 3/4 inch conduit entry and a 1/2 inch conduit entry, making it suitable for reducing connections within an enclosure knockout or between conduit sections of different trade sizes. Licensed electricians and electrical contractors install this type of fitting in commercial and industrial wiring systems.

This male union is used in rigid metal conduit and IMC installations where a serviceable, disconnectable joint is required. The 3/4 inch by 1/2 inch configuration addresses situations where a conduit run changes trade size at a junction point. Typical applications include panel entries, junction box connections, and conduit runs that require periodic maintenance access. It is suited for both new construction and retrofit electrical projects.

Key Features

• Threaded male union design allows conduit disconnection without cutting
• 3/4 inch x 1/2 inch reducing configuration for multi-size conduit runs
• Compatible with rigid metal conduit and IMC systems

Compatibility

Designed as an OEM-style replacement and standard-fit conduit union for rigid metal conduit and IMC raceway systems requiring a 3/4 inch to 1/2 inch male union connection.

Installation Notes

Installation must be performed by a qualified electrician in accordance with NFPA 70 (National Electrical Code) requirements for conduit fittings. De-energize and lock out the affected circuit before working on any conduit assembly. Use appropriate pipe wrenches or conduit tools to achieve a secure threaded connection.
