Combination Coupling, EMT to Flex Zinc Die Cast 1"

Overview

The Combination Coupling, EMT to Flex Zinc Die Cast 1" is a versatile electrical connector designed to join Electrical Metallic Tubing (EMT) conduit with flexible conduit (often referred to as flex). It features a zinc die-cast construction that provides durability, strength, and corrosion resistance. This coupling is designed to allow for seamless integration between rigid and flexible conduit systems, ensuring a secure, safe, and efficient electrical installation. The 1" size is commonly used for typical residential, commercial, and light industrial wiring applications.

Description

This combination coupling is specifically engineered for EMT to flexible conduit connections, enabling the safe and easy transition between rigid EMT conduit and more flexible conduit types, such as liquid-tight flexible conduit (LFNC) or flexible metal conduit (FMC). The zinc die-cast material ensures the coupling is both durable and resistant to environmental factors like moisture, corrosion, and impact. The design includes a threaded connection that securely fastens the EMT conduit to the flexible conduit, ensuring a tight, lasting bond.

The 1" size is commonly used for wiring systems that require a transition from a rigid conduit to a more flexible one. This allows for greater flexibility and movement of wiring in areas where the installation needs to be more adaptable.

Cases & Uses

1. Residential Wiring Systems:
   • The combination coupling is often used to transition from rigid EMT conduit to flexible conduit in residential electrical installations, such as connecting circuits to outlets or light fixtures in areas requiring flexible wiring.
2. Commercial Electrical Installations:
   • Commonly used in commercial buildings, especially where flexible conduit is needed for flexible movement of cables (e.g., in offices, factories, and other commercial spaces).
3. Light Industrial Applications:
   • Used to connect EMT conduit to flexible conduit in light industrial environments where a more adaptable conduit system is needed to protect wiring from mechanical damage or vibration.
4. Outdoor & Hazardous Locations:
   • This coupling can be used in outdoor installations or in areas subject to moisture or harsh conditions when used in conjunction with liquid-tight flexible conduit. It helps to prevent water or debris from entering the conduit, offering a reliable seal.
5. Machine Wiring:
   • Ideal for use in machine control systems, where wiring needs to be routed through both rigid and flexible sections to accommodate movement or vibration, such as in robotics, automated machinery, or HVAC systems.
6. Marinas or Waterfront Applications:
   • Used in marine environments or waterfront installations, where flexible conduit is needed to protect electrical cables that may be exposed to water or movement.
