Overview

The ABB ST11/4GR-G PVC Coated Liquitight Conduit Connector is a precision-engineered solution for 1-1/4" (35 metric) liquidtight flexible metal conduit systems. This straight connector combines a robust steel fitting with a minimum 0.040" (40 mil) PVC coating bonded to the exterior, delivering superior corrosion resistance and mechanical durability in harsh industrial environments. The integrated grounding ring, constructed from naval brass, meets UL 467 standards for reliable electrical continuity and bonding, ensuring compliance with NEC Section 351.7 for grounding applications. Designed for seamless integration with T&B Liquidtight Systems® fittings, the ST11/4GR-G features pressure-sealing sleeves that prevent moisture ingress and maintain system integrity. The dark gray PVC coating provides a professional finish while blending with existing infrastructure, and custom colors are available upon request for specialized applications. With standardized NPT taper pipe threads, this connector ensures quick, leak-proof installation and compatibility with a wide range of conduit sizes. Ideal for industrial machinery, HVAC systems, commercial electrical installations, and corrosive environments, the ST11/4GR-G is listed by UL (File #E-23018) and certified by CSA, meeting stringent performance standards for hazardous locations, including Class I, Div. 2; Class II, Div. 1 and 2; and Class III, Div. 1 and 2. The connector is manufactured in the US by ABB Installation Products, a trusted name in electrical infrastructure solutions. Key specifications include a steel body with electro-zinc plating and chromate coating, a resilient Santoprene sealing gasket, and stainless steel ground cones. The product is distributed by Gross Automation and supported by ABB’s global network of industrial distributors.
