Appleton 31-050 Malleable Compression Conduit Connector

Product Description

The APPLETON 31-050 is a 1/2-inch malleable compression conduit connector designed to secure electrical metallic tubing (EMT) to enclosures, junction boxes, and conduit bodies. Malleable iron construction provides reliable mechanical strength and resistance to deformation under torque, making it a dependable choice for raceway terminations in commercial and residential electrical installations. The compression-style fitting creates a firm, vibration-resistant connection without the need for a locknut on the conduit side. Licensed electricians and electrical contractors install this fitting as part of standard EMT raceway assemblies.

This connector is suited for 1/2-inch EMT conduit terminations in dry or damp locations, including panel enclosures, junction boxes, and electrical cabinets. It is commonly used in light commercial, industrial, and residential wiring projects where a secure, low-profile conduit termination is required. The compression design simplifies installation and reduces the risk of conduit pull-out in finished raceway systems.

Key Features

• Malleable iron body for superior strength and resistance to cracking under installation stress
• Compression-style engagement secures 1/2-inch EMT without additional locknut on conduit side
• Low-profile design suits tight enclosure knockout clearances
• Consistent thread engagement for reliable grounding continuity through the raceway

Compatibility

Designed as an OEM-style fitting for use with standard 1/2-inch EMT conduit raceway systems in commercial and residential electrical applications.

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 opening any enclosure or conduit body. Use the appropriate knockout punch or existing knockout for the 1/2-inch trade size, and tighten the compression nut fully to ensure secure conduit retention and proper grounding continuity. Do not over-torque the compression nut, as this may deform the fitting body.
