Bridgeport Fittings 290-XS EMT/Rigid to FMC Transition Coupling

Bridgeport Fittings EMT/Rigid to FMC Transition Coupling, 4" Zinc-Plated Steel

Bridgeport Fittings' EMT/Rigid to FMC transition coupling is engineered to connect EMT or rigid conduit to flexible metal conduit (FMC) within the same electrical raceway run. Constructed from zinc-plated steel, this coupling delivers a durable, corrosion-resistant connection point for electricians who need to shift from rigid or EMT conduit sections to flexible metal conduit without breaking the raceway. With a 4" to 4" sizing, this coupling is built for larger commercial and industrial conduit runs where a clean transition between conduit types is required for equipment connections, motor whips, or areas requiring flexibility. This transition coupling eliminates the need for additional adapters when a raceway must change from rigid conduit types to flexible metal conduit near equipment, panels, or areas requiring extra flexibility. As a 4" fitting, it is sized for high-capacity electrical distribution systems commonly found in industrial plants, large commercial buildings, and heavy machinery installations.

Key Features

• Trade Size: 4" to 4" transition coupling for connecting EMT or rigid conduit runs directly to flexible metal conduit (FMC).
• Durable Construction: Zinc-plated steel body resists corrosion and stands up to the demands of industrial and commercial installation environments.
• Versatile Transition Design: Accepts EMT or rigid conduit on one end and flexible metal conduit (FMC) on the other, simplifying raceway transitions without additional adapters.
• Finish: Zinc-plated steel finish provides long-term protection against rust and wear in demanding electrical environments.
• Steel Body: Solid steel construction provides the strength required for larger 4" conduit systems carrying heavier conductor loads.
