Sepco 170C Die Cast Zinc EMT-to-Flex Combination Coupling, 1/2-Inch x 3/8-Inch

Sepco 170C Die Cast Zinc EMT-to-Flex Combination Coupling, 1/2-Inch x 3/8-Inch

The Sepco 170C is a die cast zinc EMT-to-flex combination coupling engineered to join 1/2-Inch EMT (electrical metallic tubing) conduit directly to 3/8-Inch flexible conduit in a single fitting. Rather than stacking separate adapters at every transition point, this combination coupling lets electricians move from rigid EMT runs into flexible conduit sections with one compact connection. The die cast zinc body gives the 170C the strength and corrosion resistance electrical contractors expect from a raceway fitting used across commercial and industrial wiring systems. Combination couplings of this type are a common part of a conduit installer's parts inventory because branch-circuit runs frequently start in rigid EMT and finish in flexible conduit at a motor, luminaire, appliance, or piece of equipment that needs a degree of movement or vibration isolation. Having a single fitting handle that transition, rather than a set screw EMT connector paired with a separate flex connector, means fewer threaded joints, fewer potential leak or loosening points along the raceway, and a faster rough-in for the electrician on the job.

Key Features

• Trade Size: 1/2-Inch EMT x 3/8-Inch flexible conduit combination sizing for a direct transition between conduit types.
• Durable Construction: Die cast zinc body resists corrosion and holds up to the mechanical stress of everyday conduit installation and handling.
• Combination Coupling Design: A single fitting connects EMT conduit straight to flexible conduit, simplifying raceway runs and reducing the fitting count at each junction.
• Zinc Die-Cast Body: The die casting process produces a dense, uniform zinc body that holds its shape and threading through repeated installation handling.

Technical Specifications

• Refer to manufacturer documentation for complete technical specifications.

Typical Applications

• EMT to Flexible Conduit Transitions
• Commercial and Industrial Electrical Installations
• Conduit and Raceway Systems
• Renovation and New Construction Wiring
• Junction Box and Enclosure Conduit Entries

Why SEPCO?

SEPCO manufactures conduit fittings like the 170C from die cast zinc to give installers a coupling that stands up to daily jobsite handling while resisting corrosion over the life of the installation. The EMT-to-flex combination design means electricians can complete a conduit-to-flex transition with a single Sepco fitting instead of sourcing and stocking multiple separate adapters, helping keep material lists simple and installations consistent across commercial and industrial electrical projects. For contractors and maintenance crews who standardize on a short list of trusted conduit fittings, a die cast zinc combination coupling like the Sepco 170C is a straightforward way to keep an EMT-to-flex transition reliable without adding extra parts, extra labor, or extra points of failure to the raceway.
