Thomas Betts 3139 Fmc Conduit Connector 1-1/2 in Angled

Product Description

The THOMAS BETTS 3139 is an angled, insulated conduit connector designed for use with flexible metal conduit (FMC). Constructed from malleable iron, this set screw connector provides a secure mechanical connection between FMC and an enclosure or junction box knockout. The angled body geometry allows for easier routing in tight spaces where a straight connector would restrict conduit movement. At a 1-1/2 inch trade size, it suits medium-to-large FMC runs commonly found in commercial and industrial wiring applications. Licensed electricians and electrical contractors install this fitting during conduit termination work on panel feeds, motor connections, and equipment drops.

This connector is suited for non-hazardous area applications in commercial and industrial electrical installations. The 1-1/2 inch trade size accommodates correspondingly sized FMC and is a common requirement on motor branch circuits, HVAC equipment connections, and machinery feeds where flexible conduit is required by code or layout. The insulated throat protects wire insulation at the point of entry, reducing the risk of abrasion damage where conductors pass through the fitting body.

Key Features

• Angled connector body for easier conduit routing in confined spaces
• Set screw connection secures FMC mechanically without tools beyond a standard hex key
• Malleable iron construction provides durability and resistance to mechanical stress
• Insulated throat protects conductor insulation at the conduit entry point
• Rated for non-hazardous area installations
• 1-1/2 inch trade size fits standard FMC of corresponding diameter

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch flexible metal conduit (FMC) in non-hazardous electrical installations.

Installation Notes

Installation is performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for FMC terminations. De-energize the circuit and verify absence of voltage before beginning any conduit termination work. Insert the FMC into the connector body and tighten the set screw with the appropriate hex key until the conduit is firmly secured. Do not overtighten the set screw, as this can deform the FMC and compromise the mechanical connection.
