Southwire 254M Rigid Compression Coupling 1-1/4 Inch

Product Description

The SOUTHWIRE 254M is a 1-1/4 inch rigid compression coupling designed for joining sections of rigid metal conduit in electrical raceway systems. This fitting creates a secure, weatherproof mechanical connection between conduit runs without requiring threading at the joint. Compression-style couplings like the 254M are a standard choice where field-cut conduit ends need to be joined cleanly and securely. Licensed electricians install this fitting in both interior and exterior conduit systems where a reliable, code-compliant connection is required.

The 254M is suited for use in commercial and residential electrical installations where rigid metal conduit is specified. Typical applications include service entrances, exposed conduit runs in industrial facilities, outdoor installations, and anywhere rigid conduit is required by local electrical code. The compression design accommodates field-cut conduit ends and eliminates the need for threading equipment on the job site.

Key Features

• Compression-style fitting for joining rigid metal conduit without threading
• 1-1/4 inch trade size for compatibility with standard rigid conduit
• Suitable for interior and exterior conduit raceway applications
• Provides a secure mechanical connection between conduit sections

Compatibility

Designed as an OEM-style replacement and standard fitting for 1-1/4 inch rigid metal conduit raceway systems.

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 circuit and verify the absence of voltage before working on any conduit system. Ensure conduit ends are cleanly cut and deburred before seating into the coupling. Do not over-tighten the compression nut beyond hand-tight plus a firm quarter-turn, as excessive force can distort the fitting body.
