Use Bridgeport’s 583-DC 1" EMT to FMC Combination Coupling to directly connect flexible metal conduit (FMC) to electrical metallic tubing (EMT) without the need for hanging an electrical box or enclosure between the two conduit types. Die cast zinc combination couplings feature a precise fit and finish with excellent corrosion resistance for use in harsh environments. To install, simply screw the flex end directly into flexible metal conduit and then use the compression end to secure to EMT. This combination coupling is available in flex trade sizes 1/2", 3/4" and 1".
