Overview

NSi Industries 3100-US 1/2" steel rigid conduit compression coupling is a zinc-electroplated steel fitting engineered to join two 1/2" rigid or IMC conduits in raceway systems. This compression-type coupling delivers a secure, leak-proof connection critical for maintaining conduit system integrity in demanding environments. The rigid steel construction ensures long-term durability, while the zinc electroplate finish provides corrosion resistance for reliable performance in wet locations. Designed for compatibility with standard 1/2" trade size conduits, the 3100-US features a dimension A of 1.75 inches and dimension B of 1.18 inches. The coupling is CSA listed for use in wet locations and meets NEMA Standard FB-1 and Federal Specification A-A-50553A. Packaged in quantities of 100 per standard box and 25 per unit, the 3100-US offers efficient handling for large-scale projects. Ideal for industrial, commercial, and institutional applications requiring robust conduit connections in harsh or corrosive environments.
