Appleton 4-150 Malleable Iron 3-piece Conduit Coupling

Product Description

The APPLETON 4-150 is a 1-1/2 inch malleable iron three-piece conduit coupling designed for joining conduit sections in electrical raceway installations. The three-piece construction allows the coupling to be installed without rotating the conduit, making it well suited for tight or fixed runs where spinning the conduit is not practical. Built from malleable iron, it delivers the mechanical strength and durability required in commercial and industrial electrical work. Licensed electricians and electrical contractors are the primary installers of this fitting.

This coupling is used in conduit installations where a rigid, threaded connection is needed between two fixed conduit sections. The 1-1/2 inch trade size fits standard threaded rigid metal conduit (RMC) and intermediate metal conduit (IMC) of the same trade size. Typical applications include exposed conduit runs in commercial buildings, industrial facilities, and infrastructure projects where mechanical protection and code-compliant connections are required.

Key Features

• Three-piece design allows installation on fixed conduit without rotating either conduit section
• Malleable iron construction provides high impact resistance and long service life
• 1-1/2 inch trade size fits standard threaded RMC and IMC conduit
• Threaded engagement on both ends ensures a secure, rigid connection

Compatibility

Designed as an OEM-style replacement fitting for 1-1/2 inch threaded rigid metal conduit and intermediate metal conduit systems in standard electrical raceway installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for conduit fittings. De-energize all circuits in the conduit run before beginning work. Use appropriate pipe wrenches or conduit tools to achieve proper thread engagement on both ends of the coupling. Apply listed thread lubricant or thread sealant only as permitted by the applicable code and inspection authority.
