SEPCO 171C Zinc Die-Cast Combination Coupling for EMT-to-Flex Conduit Transitions

SEPCO 171C Zinc Die-Cast Combination Coupling for EMT-to-Flex Conduit Transitions

The SEPCO 171C is a zinc die-cast combination coupling engineered to join rigid electrical metallic tubing (EMT) directly to flexible conduit within a single raceway run. This family of combination couplings is available in trade sizes from 1/2" through 1" to match the raceway system on the job, giving contractors one dependable fitting for EMT-to-flex transitions instead of pairing a separate EMT coupling with a separate flex connector. Built from a zinc die-cast body across every trade size in the range, the 171C series delivers the corrosion resistance and mechanical strength electrical contractors rely on for commercial and industrial installations where a flexible whip must connect back to a rigid EMT raceway.

Key Features

• Trade Size Range: Offered in 1/2", 3/4", and 1" trade sizes so the fitting matches the EMT and flexible conduit runs on the job.
• Combination Design: Joins EMT conduit directly to flexible conduit in a single fitting, eliminating the need for two separate fittings at the transition point.
• Durable Zinc Die-Cast Construction: The zinc die-cast body resists corrosion and provides the mechanical strength needed for demanding commercial and industrial electrical installations.
• EMT-to-Flex Transition: Purpose-built for connecting rigid EMT raceway runs to flexible conduit, commonly used where a whip is needed at a motor, fixture, or piece of equipment.
• Simplified Installation: A single combination coupling replaces multiple standalone fittings, saving installation time and reducing potential failure points along the raceway.
• Compact Coupling Body: Zinc die-cast construction keeps each trade size in the range compact and easy to install in tight panel, junction box, and equipment enclosures.

Technical Specifications

• Trade Size: 1/2" - 1"
