Overview

The ABB 2931 Liquidtight Strain Relief Connector is a precision-engineered cable fitting designed for secure, strain-free entry into industrial enclosures. This straight-style connector features a 3/4-inch trade size hub with a 13/16-inch throat diameter, accommodating cord diameters from 0.310 to 0.560 inches. Constructed from durable steel with a zinc-plated finish, the connector provides robust mechanical protection against physical stress and environmental contaminants. The integrated rubber bushing delivers a watertight and oil-resistant seal, ensuring reliable performance in wet or dry locations. The gland nut and grip assembly form a non-slip connection that prevents cable pull-out while maintaining grounding continuity for armored or unarmored cables. This design reduces stress at the entry point, extending cable life in demanding applications. Ideal for use in manufacturing plants, outdoor installations, and commercial facilities, the ABB 2931 is compatible with standard liquidtight flexible conduit systems. Its compact design fits into tight spaces, making it suitable for control and power cable applications where space is constrained. The connector supports cable types including S, SO, SV, ST, STD, SJ, SJO, SJT, SJTO, and SVD, providing versatility across a range of industrial environments. Key specifications include a steel body with zinc plating, a 3/4-inch hub size, and a cable range of 0.310 to 0.560 inches. The straight configuration ensures straightforward installation, while the rubber bushing and gland nut work together to maintain a secure, sealed connection. This product is engineered for applications requiring reliable cable protection and long-term durability in harsh conditions.
