Bridgeport Fittings Malleable Iron Combination Coupling, Liquidtight to Rigid/IMC Conduit

The Bridgeport Fittings combination coupling is engineered to transition liquidtight flexible conduit (LFMC) into rigid or IMC threaded conduit runs within a single fitting, available in trade sizes from 3/4\" through 1-1/2\" to match a range of conduit runs. Built from malleable iron for impact resistance and long-term durability, the coupling includes a steel ferrule that locks the liquidtight flexible conduit connection tightly in place, while the opposite threaded end mates directly to rigid or IMC conduit for a secure, code-compliant transition. This combination design lets electricians make a clean transition between conduit types at one junction point instead of installing two separate fittings, saving material, reducing the number of connections in a run, and simplifying labor on the job. This family of fittings is built for professional electrical installations where liquidtight flexible conduit must be joined to a rigid or IMC conduit system through a single, reliable fitting.

Key Features

  • Trade Size Range: Available in 3/4\" and 1-1/2\" sizing to connect liquidtight flexible conduit runs to rigid or IMC threaded conduit.
  • Durable Construction: Malleable iron body construction provides strength, impact resistance, and long service life in commercial and industrial conduit systems.
  • Steel Ferrule: An internal steel ferrule reinforces the liquidtight flexible conduit connection point, helping the joint stay tight and secure even under vibration and repeated conduit movement.
  • Combination Coupling Design: Combines a liquidtight flex conduit fitting and a rigid/IMC threaded coupling in a single compact body, reducing the number of separate fittings needed at a conduit transition point.
  • Threaded Conduit Connection: The threaded end of each fitting delivers a secure mechanical and electrically continuous bond to rigid or IMC conduit sections.
  • One-Piece Fitting Body: A single malleable iron body handles both the liquidtight flex termination and the rigid/IMC threaded connection, streamlining conduit runs and cutting down on installation time.
  • Corrosion Resistance: Malleable iron construction stands up to the wear and handling common on commercial and industrial job sites.

Why Bridgeport Fittings?

Bridgeport Fittings manufactures this combination coupling family from malleable iron with a reinforcing steel ferrule, giving contractors a rugged fitting built for demanding conduit installations across a range of trade sizes. By combining a liquidtight flexible conduit connection and a rigid/IMC threaded coupling into one fitting, this coupling helps electricians deliver a dependable, code-compliant conduit transition without stacking multiple separate parts at a single junction box or enclosure. It is a straightforward, purpose-built solution for jobs that call for a secure bridge between liquidtight flex and rigid or IMC conduit, whether the run calls for a 3/4\" or 1-1/2\" fitting.

Bridgeport Fittings 4371-LT – Frequently Asked Questions

1) Does this coupling connect liquidtight flex directly to rigid conduit without a second fitting?
That is exactly what it does. One malleable iron body terminates liquidtight flexible conduit (LFMC) on one end and threads onto rigid or IMC conduit on the other, so you make the transition at a single point instead of stacking a liquidtight connector and a separate threaded coupling.
2) Will the threaded end mate to IMC as well as rigid conduit?
Yes. The threaded end is made to mate with either rigid metal conduit or IMC, since both use the same conduit thread. Connection type on the fitting is threaded, so you are screwing it onto the conduit end, not compressing or setscrewing it.
3) Is a malleable iron combination coupling worth it over a die-cast fitting for a motor connection?
For motor, pump and equipment drops the malleable iron body is the reason to pick it. Those runs see vibration and repeated movement, and the fitting adds an internal steel ferrule that reinforces the liquidtight side so the joint stays tight under that movement. Die-cast bodies are lighter duty and more prone to damage from job site handling and impact.
4) Does this fitting maintain ground continuity through the conduit transition?
The threaded end gives a mechanical and electrically continuous bond to the rigid or IMC section, and the body is malleable iron rather than a non-conductive material, so the metallic path carries through the fitting. Bonding of the liquidtight side still follows whatever your installation requires for that flex type.
5) What does the steel ferrule do, and do I need any extra parts to land the liquidtight?
The ferrule is internal to the fitting and clamps the liquidtight flexible conduit so the joint holds under vibration. It ships as part of the coupling, so the liquidtight side needs nothing added. The only thing you supply is the threaded rigid or IMC conduit on the other end.
6) Can I use this to bring flex into a junction box?
No, that is not what this part is. A combination coupling joins two lengths of conduit to each other, liquidtight flex to rigid or IMC. To enter a box or enclosure you need a connector with a locknut and box hub, not a coupling.
7) I need to standardize fittings across a facility with both 3/4 inch and 1-1/2 inch conduit. Are these the same design in both sizes?
Same family, same construction in both: malleable iron body with a steel ferrule and a threaded rigid/IMC end. The difference is trade size only, 4371-LT for 3/4 inch and 4374-LT for 1-1/2 inch, so an MRO stock can carry both with one install procedure.
