Overview

The ABB ST490-G PVC Coated Liquitight Conduit Connector is a 90-degree, 4-inch (103 metric) steel fitting engineered for industrial-grade electrical and mechanical installations requiring corrosion resistance and structural integrity. This connector features a minimum 0.040-inch (40 mil) PVC coating bonded to the exterior of a steel fitting, providing superior protection against chemicals, moisture, abrasion, and harsh environmental conditions. The dark gray PVC coating ensures compatibility with standard industrial color schemes while enhancing UV and chemical resistance. Designed for use with Liquitight flexible conduit systems, the ST490-G delivers a secure, watertight connection that minimizes installation time and maintenance costs. The pressure-sealing sleeves protect the connection points, ensuring long-term reliability in demanding applications such as manufacturing plants, refineries, wastewater treatment facilities, and outdoor electrical installations. The connector meets UL 467 grounding and bonding standards, with a ground ring made from naval brass for enhanced corrosion resistance. The ST490-G is part of ABB’s Ocal corrosion-resistant conduit system, which utilizes genuine T&B Liquidtight Systems fittings to guarantee quality installations. Standard color is dark gray (G), but custom colors are available upon request for specialized applications. This connector is compatible with standard 4-inch pipe sizes and integrates seamlessly with existing ABB Liquitight conduit systems, making it ideal for new construction, retrofits, and upgrades in industrial, commercial, and infrastructure projects. With a focus on durability and performance, the ST490-G ensures dependable operation in corrosive environments where electrical integrity and mechanical strength are critical.
