Product Description EMT to Rigid Conduit Fittings Steel Combination Coupling with Zinc Plated Rigid Compression ConnectorProduct DescriptionELECMAN? UL Certificate Steel EMT to Rigid Combination Coupling Compression / Thread TypePRODUCTEMT to Rigid Combination Coupling MATERIALSteelTYPECompression / Thread TypeProduct IntroductionThis is a specialized electrical fitting designed to join two different types of metal conduit together securely and create a weatherproof seal. Specifically, it connects EMT (Electrical Metallic Tubing) to Rigid Steel Conduit (often abbreviated as RMC or simply "Rigid").The ELECMAN ? Steel EMT to Rigid Combination Coupling Compression is a crucial adapter fitting used to create a secure, code-compliant, and weatherproof transition between two different types of metal conduit systems. It is the essential link where the lightweight, cost-effective nature of EMT meets the rugged, durable protection of Rigid Steel conduit.FeaturesThe features of this combination coupling are all engineered for one primary goal: to create a secure, sealed, and code-compliant transition between the lightweight, thin-wall EMT system and the heavy-duty, thick-wall Rigid conduit system.1. Dual Connection Mechanism (The Core Feature)EMT Side (Compression Type): One end uses a compression nut and ring (ferrule) to create a secure, weatherproof seal on the smooth, thin wall of EMT conduit.Rigid Conduit Side (Threaded Type): The other end has standard straight (NPSM) threads designed to accept the pre-threaded end of a piece of Rigid Steel Conduit (RMC).2. Three-Piece ConstructionThe fitting typically consists of three separate steel components:A central coupling body with internal threads on one end.A compression nut for the EMT side.A compression ring (ferrule) that gets compressed against the EMT.3. Weatherproof and Rain-Tight SealPurpose: The compression mechanism on the EMT side is designed to form a tight, 360-degree seal around the conduit.Benefit: This rain-tight feature prevents moisture, dust, and debris from entering the electrical system at the transition point, making it suitable for outdoor and wet location applications.4. Secure Mechanical ConnectionEMT Side: The compression nut is wrench-tightened, forcing the ring to clamp down evenly on the EMT, providing a vibration-resistant grip that is stronger than set screws.Rigid Side: The threaded connection provides a robust, mechanically strong link that is characteristic of all Rigid conduit systems.5. Maintains Grounding ContinuityPurpose: The all-steel construction and secure metal-to-metal contact ensure a reliable electrical bond.Benefit: This maintains the grounding path through the conduit system, which is a critical safety function.6. Standard Trade SizesPurpose: Manufactured to match standard conduit sizes.Benefit: Ensures a perfect fit. Common sizes include 1/2", 3/4", 1", and larger, corresponding to the sizes of both EMT and Rigid conduit.Application The application of the ELECMAN ? Steel EMT to Rigid Combination Coupling Compression is highly specific and critical for transitioning between different levels of mechanical protection and environmental exposure in an electrical conduit system.1.
