Thomas Betts 8421 Conduit Connector 1-1/4 in Rigid Imc

Product Description

The THOMAS BETTS 8421 is a straight, compression-style conduit connector designed for use with rigid metal conduit (RMC) and intermediate metal conduit (IMC) in a 1-1/4 inch trade size. Constructed from malleable iron, it provides a durable, non-insulated mechanical connection at the point where conduit enters an enclosure, panel, or junction box. This fitting is suited for commercial and industrial electrical installations where a reliable, code-compliant conduit termination is required. Licensed electricians and electrical contractors are the primary installers of this fitting in non-hazardous locations.

This connector is used in non-hazardous area wiring applications where rigid or IMC conduit must be terminated at an electrical enclosure. The compression connection type provides a secure mechanical grip on the conduit without requiring threading at the termination point. Typical install scenarios include panel terminations, junction box entries, and conduit stub-up connections in commercial, industrial, and residential service installations.

Key Features

• Compression connection type for a secure, tool-tightened mechanical grip on conduit
• Straight connector shape for direct conduit-to-enclosure entry
• Malleable iron construction for strength and durability in demanding environments
• Non-insulated design suitable for standard non-hazardous location wiring
• 1-1/4 inch trade size fits standard RMC and IMC conduit of that designation

Compatibility

Designed as an OEM-style fitting for use with 1-1/4 inch trade size rigid metal conduit and intermediate metal conduit (IMC) in non-hazardous electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the enclosure or panel before installing or removing conduit fittings. Use the appropriate conduit wrenches or pliers to tighten the compression nut to a secure, watertight fit without over-torquing the malleable iron body. Verify the conduit trade size matches the fitting before installation.
