Overview

The ABB TK123US Set Screw Coupling is a zinc-plated steel coupling engineered for secure, concrete-tight connections in 1-inch EMT (Electrical Metallic Tubing) conduit systems. This coupling eliminates the need for conduit threading, simplifying installation while ensuring compliance with industry standards. The durable zinc plating provides excellent corrosion resistance, making it suitable for harsh environmental conditions, including outdoor and industrial applications. Key features include a hardened hex head set screw that captivates to prevent loosening from vibration, ensuring a reliable bond. The coupling is furnished with a nylon insulated throat, which reduces wire pulling effort by up to 50% and prevents insulation thinning or first-thread damage during installation. The positive center stop ensures proper alignment and a tight fit, meeting UL 514B, CSA C22.2 No. 18, and NFPA 70-1999 (ANSI) standards. Additionally, the TK123US is UL Listed (File No: E-23018) and CSA Certified (LR-2884, LR-4484), confirming its suitability for concrete-tight applications and hazardous locations where general-purpose equipment is permitted by NEC standards. Ideal for electrical contractors, facility managers, and industrial installers, the ABB TK123US coupling delivers dependable performance in commercial, industrial, and utility settings. Its robust construction and compliance with federal specifications (W-F-408, H-28) ensure long-lasting, code-compliant conduit connections. Trust ABB Installation Products for reliable, high-quality fittings that enhance the safety and efficiency of your electrical installations.
