Southwire MNT-2768 Rigid Compression Coupling 3-1/2 in

Product Description

The SOUTHWIRE MNT-2768 is a no-thread malleable iron rigid compression coupling designed to join rigid metal conduit (RMC) and intermediate metal conduit (IMC) sections without the need for threading. This fitting uses a compression-style connection to create a secure, low-profile mechanical joint suited for conduit runs in commercial and industrial electrical installations. At 4.925 pounds, the malleable iron construction provides durability in demanding environments. Licensed electricians and electrical contractors typically install this coupling as part of a code-compliant conduit system.

This coupling is sized for 3-1/2 inch conduit and is appropriate for use in commercial construction, industrial facilities, and infrastructure projects where RMC or IMC conduit is specified. The no-thread design simplifies field installation by eliminating the need for a pipe threader, making it a practical choice for field cuts and retrofit work in both new construction and maintenance applications.

Key Features

• No-thread compression design eliminates the need for field threading equipment
• Compatible with 3-1/2 inch rigid metal conduit and intermediate metal conduit
• Malleable iron construction for durability in commercial and industrial environments
• Compression-style mechanical joint for secure conduit connections
• One-year limited warranty

Compatibility

Designed as an OEM-style replacement and standard fitting for 3-1/2 inch rigid metal conduit and intermediate metal conduit systems in commercial and industrial 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 all circuits in the conduit run before beginning work. Ensure conduit ends are cleanly cut and deburred before seating into the coupling to achieve a proper compression seal. Do not over-tighten compression hardware beyond manufacturer recommendations, as this may damage the fitting body.
