Southwire IML-42-1 Insulated Flex Conduit Connector 1/2 Inch

Product Description

The SOUTHWIRE IML-42-1 is a straight, insulated malleable iron squeeze-type connector designed for terminating 1/2-inch flexible metal conduit (Greenfield) at an electrical box. The insulated throat protects wire insulation from abrasion at the conduit end, while the malleable iron body delivers reliable mechanical strength. Electricians use this connector to secure flexible conduit runs to junction boxes, panels, and enclosures in both new construction and retrofit wiring work. The squeeze-style design allows tool-free conduit engagement, simplifying installation in tight spaces.

This connector is suited for residential and light commercial electrical installations where 1/2-inch flexible metal conduit transitions into a knockout opening on an electrical enclosure. Typical applications include motor connections, appliance hook-ups, and branch circuit wiring where a short flex whip is required to provide vibration isolation or accommodate equipment movement. It is installed by licensed electricians following NEC guidelines for flexible metal conduit terminations.

Key Features

• Insulated malleable iron construction protects conductors at the conduit throat
• Straight body design for direct box-entry installations
• Squeeze-type conduit retention simplifies field installation
• Sized for 1/2-inch flexible metal conduit (Greenfield)
• Compatible with standard knockout openings on electrical enclosures

Compatibility

Designed as an OEM-style replacement connector for use with 1/2-inch flexible metal conduit terminations at standard electrical enclosure knockouts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for flexible metal conduit fittings. De-energize the circuit and verify absence of voltage before working inside any enclosure. Insert the conduit into the connector body until the squeeze mechanism engages, then thread the locknut onto the connector and tighten securely against the enclosure wall to maintain a solid mechanical connection.
