Overview

The NSI Industries 4373-LT Transition Coupling is engineered to provide a code-compliant, liquid-tight connection between Rigid/IMC conduit and Liquidtight Flexible Metal Conduit (FMC). This 1-1/4 inch coupling features NPT threads for secure attachment to enclosures and boxes, ensuring a dust-tight and watertight seal meeting NEMA Type 4 and Type 6 enclosure requirements when used with conduit. Its robust thermoplastic construction offers high mechanical pullout strength and resistance to chemicals, while the unique component design, including a sealing 'O' ring, simplifies installation and guarantees a positive seal. The smooth insulated body provides maximum dielectric strength. This coupling is designed to prevent conduit pullout and severe bends, enhancing system reliability. It aligns with Federal Standards W-F-408 and W-F-406, and Federal Standard H-28 for threads. The SKU 4373-LT is a reliable solution for industrial electrical applications requiring dependable liquid-tight conduit transitions, saving time and labor during installation. It is distributed by Gross Automation.
