Thomas Betts 8720 Conduit Coupling 2-1/2 in Rigid Imc

Product Description

The THOMAS BETTS 8720 is a malleable iron conduit coupling designed for use with rigid metal conduit (RMC) and intermediate metal conduit (IMC) at a 2-1/2 inch trade size. It uses a compression-style connection to create a concrete-tight fitting without threading, making it well suited for installations where a secure, moisture-resistant mechanical connection is required. Licensed electricians and electrical contractors install this coupling during conduit runs in commercial and industrial settings. The malleable iron construction provides the durability needed in demanding environments. It ships as a single unit and is non-insulated.

This coupling is used in electrical conduit systems requiring concrete-tight performance at a 2-1/2 inch trade size. It is appropriate for both rigid metal conduit and IMC installations in concrete encasement, underground, or exposed applications where a compression fitting meets the required area-of-application rating. It is commonly installed during new construction or conduit extension work in commercial, industrial, and heavy-duty residential electrical systems.

Key Features

• Compression connection type — no threading required for a secure, concrete-tight fit
• Rated concrete-tight for use in direct-encasement and demanding wet environments
• Compatible with both rigid metal conduit (RMC) and intermediate metal conduit (IMC)
• Malleable iron construction for strength and resistance to mechanical stress
• Non-insulated design for standard conduit coupling applications
• 2-1/2 inch trade size for larger conduit runs

Compatibility

Designed for use with 2-1/2 inch trade size rigid metal conduit (RMC) and intermediate metal conduit (IMC) in concrete-tight conduit system installations.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for conduit fittings. Power down all circuits in the affected conduit run before beginning work. Compression fittings require proper seating and tightening with appropriate hand tools to achieve the concrete-tight rating — do not over-tighten or impact-drive the fitting. Verify the conduit ends are clean, deburred, and free of damage before making the connection.
