Frequently Asked Questions

What is the BRIDGEPORT FITTINGS Expansion Set Screw Coupling used for?

This steel coupling joins sections of rigid metal conduit (RMC) in electrical raceway systems. It is used in industrial and commercial installations where conduit must accommodate thermal expansion or contraction, ensuring a secure, grounded connection without insulation.

What are the specifications of the BRIDGEPORT FITTINGS EC-125R coupling?

The EC-125R is a non-insulated steel expansion set screw coupling with a 1 1/4 in trade size and 8 in overall length. It is compatible with RMC conduit and manufactured by BRIDGEPORT FITTINGS. The coupling uses set screws to secure conduit ends.

Where to buy BRIDGEPORT FITTINGS expansion couplings worldwide?

3G Electric supplies BRIDGEPORT FITTINGS expansion set screw couplings worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time on the EC-125R.

How to install a BRIDGEPORT FITTINGS expansion set screw coupling?

Slide the coupling over the ends of two RMC conduit sections, leaving a gap for expansion as per local code. Tighten the set screws evenly with a screwdriver to secure each conduit end. Ensure the coupling is not insulated and provides a continuous ground path.
