Overview

The NSi Industries 248-SBLU EMT Coupling is a color-coded, steel conduit coupling designed for secure and corrosion-resistant electrical connections in industrial and commercial applications. This 3-1/2" coupling features a nominal 0.002" (2 mil) blue urethane coating on the interior and hot-dipped galvanized threads for enhanced durability and adhesion. The exterior is coated with a minimum 0.040" (40 mil) PVC layer bonded to the steel, providing robust protection against environmental factors. The coupling includes molded ribs on the outer coating for easier installation and pressure-sealing sleeves to ensure leak-proof connections. UL verified for adhesion performance, this coupling withstands 240 hours of oven conditioning at 212°F, 600 hours of salt fog exposure, and peel testing for reliability. Ideal for electrical contractors, facility managers, and maintenance professionals, the 248-SBLU simplifies inventory management with its color-coding system and meets industry standards for long-lasting performance in conduit systems.
