SEPCO S1016 Zinc-Plated Steel EMT Compression Coupling

SEPCO S1016 Zinc-Plated Steel EMT Compression Coupling

The SEPCO S1016 EMT Compression Coupling joins two lengths of Electrical Metallic Tubing (EMT) into a single, continuous raceway run. This family is available across trade sizes ranging from 1/2" through 4" (including 1-1/4", 1-1/2", 2", 2-1/2", 3", 3-1/2", and 4"), so contractors can match the coupling to nearly any EMT conduit diameter on the job. Every size in the S1016 family is built from zinc-plated steel, pairing the mechanical strength of a steel fitting with a corrosion-resistant finish suited to demanding commercial and industrial electrical environments. The compression-style connection clamps securely around each length of EMT, forming a tight mechanical and electrical bond without relying on set screws, so contractors get a dependable, code-conscious joint from box to box.

Key Features

• Trade Size Range: Offered in 1/2" through 4" trade sizes so the coupling matches the EMT conduit run being extended, with no single size representing the whole family.
• Zinc-Plated Steel Construction: Every coupling body in this family is manufactured from steel with a zinc-plated finish, giving it the mechanical strength needed for raceway support along with added resistance to rust and corrosion over the life of the installation.
• Compression-Type Connection: A compression coupling design draws two conduit ends together and clamps down evenly around the tubing, producing a secure mechanical grip and reliable electrical continuity between conduit sections.
• Set-Screw-Free Design: Because the connection is compression-based rather than set-screw based, there are no screws to back out or loosen over time, helping maintain a consistent, dependable joint across every trade size in the family.
• EMT Compatibility: Purpose-built for Electrical Metallic Tubing (EMT), the thin-wall steel raceway commonly used in commercial and light industrial wiring systems.
• Straight-Run Coupling Function: Use this fitting to extend a conduit run in a straight line, connecting two lengths of EMT end-to-end within a raceway system, regardless of which trade size is selected.
