Bridgeport Fittings 4156-DC Mighty-Merge EMT to Duplex AC/FMC Coupling, 1/2" to 3/8", Die-Cast Zinc

The Bridgeport Fittings 4156-DC Mighty-Merge® combination coupling is designed to join 1/2" EMT conduit directly to 3/8" duplex AC (armored cable) or FMC (flexible metal conduit) runs using a single, compact fitting body. Manufactured from die-cast zinc, this combination coupling delivers a durable, corrosion-resistant connection point for electricians who need to transition between rigid EMT and flexible or armored cable systems without stocking multiple separate fittings. The Mighty-Merge® design combines two distinct connection types, EMT on one end and duplex AC/FMC on the other, into one fitting, cutting down on installation steps, inventory, and labor time on the jobsite. This 1/2" to 3/8" coupling is well suited for panel connections, junction box transitions, and general branch-circuit wiring where EMT meets flexible or armored cable. Electrical contractors can rely on this Bridgeport Fittings coupling to simplify rough-in work while maintaining a secure, code-oriented connection between conduit types.

Key Features

  • Trade Size: Provides a 1/2" EMT connection paired with a 3/8" duplex AC or FMC connection in one fitting body.
  • Durable Construction: Die-cast zinc construction offers corrosion resistance and long-term durability for demanding jobsite conditions.
  • Combination Coupling Design: The Mighty-Merge® combination design merges EMT and duplex AC/FMC connections into a single fitting, eliminating the need for separate transition couplings.
  • Simplified Transitions: Streamlines the transition from rigid EMT conduit runs into flexible armored cable or flexible metal conduit without additional adapter fittings.
  • Reduced Installation Time: Combining two connection points into a single fitting reduces the number of parts electricians must carry, install, and torque on the job.
  • Compact Fitting Body: The die-cast zinc body is engineered for a low-profile fit in tight panel and junction box locations.

Why Bridgeport Fittings?

Bridgeport Fittings developed the Mighty-Merge® line to address the everyday challenge of transitioning between different conduit and cable types on the jobsite, and the 4156-DC combination coupling carries that engineering forward with a die-cast zinc body built for durable, dependable connections. By combining an EMT connection with a duplex AC/FMC connection in a single fitting, Bridgeport Fittings helps electrical contractors simplify their rough-in work, reduce the number of separate fittings they need to stock, and maintain reliable conduit-to-cable transitions on every job. Choose Bridgeport Fittings for electrical fittings engineered to perform in real-world commercial and residential installations.

Bridgeport Fittings 4156-DC – Frequently Asked Questions

1) What does the Bridgeport 4156-DC coupling connect?
The 4156-DC Mighty-Merge coupling joins 1/2 inch EMT on one end to 3/8 inch duplex AC (armored cable) or FMC (flexible metal conduit) on the other. Duplex means the AC/FMC end takes two cables, not one. It is a single fitting body, so you don't need a separate EMT coupling plus an AC/FMC connector to make the transition.
2) Is the 4156-DC meant to go into a panel or box knockout, or between two conduit runs?
It is a coupling, not a connector, so it joins the two raceways to each other rather than terminating into an enclosure knockout. Bridgeport lists it for panel connections, junction box transitions and general branch-circuit wiring where an EMT run meets flexible or armored cable. If you need to land in a knockout with a locknut, you want a combination connector instead.
3) Is the Bridgeport 4156-DC metal or plastic, and will it hold up in a damp mechanical room?
The body is die-cast zinc, which Bridgeport specifies for corrosion resistance and durability in jobsite conditions. It is a metal fitting throughout, so it maintains the metallic path between the EMT and the AC/FMC armor.
4) Why use a combination coupling instead of two separate fittings for an EMT to AC transition?
Two-fitting transitions mean an EMT coupling, a separate AC/FMC connector and a nipple or box between them. The Mighty-Merge 4156-DC merges both connection types into one body, so there are fewer parts to stock, fewer joints to make up, and a lower profile where the transition lands in a tight panel or box location. For a standardizing MRO stockroom it also cuts two line items to one.
