Overview

The ABB TK127US Set Screw Coupling is a zinc-plated steel fitting designed for secure, reliable connections in 2-1/2 inch EMT (Electrical Metallic Tubing) conduit systems. This coupling provides a concrete-tight seal when properly taped, preventing concrete ingress during poured-in-place installations. The set screw mechanism ensures positive holding strength, eliminating conduit movement and maintaining system integrity. Constructed from durable steel, the TK127US offers corrosion resistance and long-term performance in demanding commercial and industrial environments. 18, with listings under UL File No: E-23018 and CSA File Nos: LR-2884, LR-4484. It conforms to NFPA 70-1999 (ANSI), NEMA FB1, Federal Specification W-F-408, and Federal Standard H-28 (Threads). The insulated throat design reduces wire pulling effort by up to 50%, protecting conductor insulation and preventing first thread damage during installation. This set screw coupling eliminates the need for threading, offering faster installation compared to traditional threaded fittings. Ideal for connecting EMT conduit to enclosures or coupling conduit runs in commercial buildings, industrial facilities, and infrastructure projects where reliable conduit connections are critical. The TK127US is part of a comprehensive EMT fitting system that includes sizes from 1/2 inch through 4 inches, providing consistent performance across conduit systems.
