Cooper Crouse-hinds 662 Emt Conduit Coupling 1 Inch

Product Description

The COOPER CROUSE-HINDS 662 is a compression-style coupling designed for connecting 1-inch trade size EMT (electrical metallic tubing) conduit sections. Fabricated from steel with a non-insulated construction, this fitting creates a concrete-tight connection without the need for tools beyond basic hand tightening. It is rated for concrete-tight applications, making it suitable for installations where conduit runs are embedded in or in contact with concrete. Electricians and electrical contractors install this coupling as part of EMT conduit systems in commercial and residential electrical work.

This coupling is intended for use with 1-inch trade size EMT conduit in standard electrical conduit runs. Its concrete-tight rating makes it appropriate for slab pours, below-grade applications, and other installations where moisture resistance and physical protection of the conduit joint are required. The compression connection type provides a secure mechanical fit without set screws, reducing installation time in high-volume rough-in work.

Key Features

• Compression connection type for tool-free, set-screw-free installation
• Concrete-tight rated for embedded or moisture-exposed conduit runs
• Steel construction for mechanical durability in commercial and residential applications
• Non-insulated design for standard EMT coupling use
• 1-inch trade size fits standard 1-inch EMT conduit

Compatibility

Designed as an OEM-style fitting for use with 1-inch trade size EMT conduit systems in standard 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. Compression couplings require proper seating of both conduit ends into the fitting body before tightening the compression nut to ensure a secure, concrete-tight joint. Do not over-tighten, as this may deform the compression ring and compromise the seal.
