Overview

The ABB TK112US Compression Coupling is a zinc-plated steel fitting engineered for secure, concrete-tight connections in 3/4-inch EMT (Electrical Metallic Tubing) conduit systems. Designed for industrial, commercial, and residential electrical installations, this coupling provides a permanent, vibration-resistant joint that resists corrosion in harsh environments. The compression design ensures a firm grip on the conduit, eliminating movement and maintaining system integrity over time. The zinc-plated steel construction meets UL and CSA certifications, confirming compliance with North American electrical standards (UL File No. E 09043, CSA File No. 2884). This coupling is ideal for applications requiring a watertight seal in concrete-encased conduit runs, such as underground wiring, outdoor installations, or areas exposed to moisture. Unlike standard couplings, the TK112US is specifically rated for concrete-tight use, preventing water ingress and protecting conductors from environmental damage. The coupling’s durable finish resists rust and corrosion, ensuring long-term reliability in industrial facilities, utility rooms, or commercial buildings. Compatible with all 3/4-inch EMT conduit, this coupling simplifies installation by eliminating the need for threading or additional sealing compounds. Trusted by electricians and contractors, the TK112US delivers a cost-effective, high-performance solution for secure conduit connections in demanding applications.
