Cooper Crouse-hinds 665 Emt Coupling 2 Inches Compression

Product Description

The COOPER CROUSE-HINDS 665 is a compression-style EMT conduit coupling designed to join two lengths of electrical metallic tubing in a secure, concrete-tight connection. Made from steel construction, this non-insulated fitting delivers a reliable mechanical and electrical bond without the need for set screws. It suits installations where moisture resistance and structural integrity are critical, including embedment in concrete or use in wet locations. Licensed electricians install this coupling during conduit rough-in work on commercial and residential projects.

This coupling is appropriate for use with 2-inch trade size EMT conduit runs in commercial construction, industrial facilities, and residential wiring systems. Compression fittings like the 665 are favored in concrete pour applications and wet-area installations where set-screw fittings may not provide adequate environmental protection. The concrete-tight rating makes it suitable for direct embedment or surface runs in damp and wet locations.

Key Features

• Compression connection type - no set screws required, tool-tightened for a secure fit
• Concrete-tight construction suitable for embedment and wet-location conduit runs
• 2-inch trade size fits standard EMT conduit of the same trade designation
• Steel material provides mechanical strength and grounding continuity
• Non-insulated design for standard EMT coupling applications

Compatibility

Designed for use with 2-inch trade size EMT conduit as an OEM-style compression coupling fitting.

Installation Notes

Installation of EMT conduit fittings must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits in the work area before handling conduit or fittings. Use an appropriate compression tool or wrench to tighten the fitting body to the conduit - do not over-torque the coupling nut. Inspect the conduit ends for burrs or deformation before assembly to ensure a proper seal.
