Overview

The ABB TC719US Compression Connector is a zinc-plated steel fitting engineered specifically for 3-1/2" EMT conduit installations that require a concrete-tight, insulated connection. This compression-style connector ensures a secure, vibration-resistant joint that meets UL 514B and CSA C22.2 No. 18 standards, making it ideal for demanding industrial, commercial, and construction applications where electrical integrity and mechanical durability are critical. Constructed from durable steel with a zinc-plated finish, the TC719US resists corrosion and provides long-term reliability in harsh environments, including those exposed to moisture, chemicals, or extreme temperatures. Its insulated throat reduces wire-pulling effort by up to 50%, significantly simplifying installation while maintaining electrical safety and preventing damage to conductors. Certified for concrete-tight applications, this connector eliminates the need for conduit threading, streamlining workflows in electrical infrastructure projects by reducing labor time and material costs. The 3.970-inch length is precisely designed to accommodate standard 3-1/2" EMT conduit sizes, ensuring a proper fit and secure connection without the risk of misalignment or gaps. The compression connection type delivers consistent performance across temperature variations, maintaining a tight seal even in fluctuating environmental conditions. This connector is part of ABB’s Installation Products line, known for compliance with industry standards and high-quality fittings that enhance system safety and operational efficiency. With its robust construction and specialized features, the TC719US is a reliable solution for electrical installations requiring durable, code-compliant conduit connections.
