SEPCO S1116 Series Zinc-Plated Steel EMT Set-Screw Coupling

SEPCO S1116 Series Zinc-Plated Steel EMT Set-Screw Coupling

The SEPCO S1116 Series Zinc-Plated Steel EMT Set-Screw Coupling joins two lengths of EMT (Electrical Metallic Tubing) conduit into a single, continuous raceway using a tool-only set-screw connection. Built from zinc-plated steel for corrosion resistance and mechanical strength, this coupling is available in trade sizes from 1/2" through 4", covering common branch-circuit and larger feeder conduit runs. The slip-fit body and set-screw design let electricians make up a secure mechanical and electrical connection without soldering, welding, or compression tools, making it a straightforward, code-familiar way to extend or repair EMT conduit on commercial, industrial, and residential jobs.

Key Features

• Trade Size Range: Offered in trade sizes from 1/2" through 4" to match the EMT conduit size used on the job.
• Durable Construction: Zinc-plated steel body resists corrosion and rust while standing up to the physical demands of conduit installation and handling.
• Set-Screw Connection: A set-screw design lets installers make up a secure mechanical and electrical bond between EMT conduit sections using only a screwdriver or nut driver, with no soldering or threading required.
• EMT Compatibility: Sized and designed specifically for use with EMT conduit, keeping the raceway system consistent from run to run.
• Secure Raceway Continuity: Once tightened, the coupling holds conduit sections in solid alignment, supporting continuous grounding and a rigid mechanical path through the raceway.
• Field-Friendly Installation: The slip-fit, set-screw style is quick to install and reposition during rough-in, helping crews keep conduit runs moving on schedule.
• Zinc-Plated Finish: The plated finish provides a clean, uniform surface that helps the fitting hold up in typical indoor electrical environments.
