Overview

The ABB 2931SST is a 3/4-inch NPT threaded, straight-style liquidtight strain relief connector designed for secure cable entry into enclosures and equipment. Constructed from durable 304 stainless steel, this connector delivers exceptional corrosion resistance in wet, caustic, or chemically aggressive environments while maintaining electrical system integrity. The integrated neoprene bushing provides effective strain relief, protecting cables from damage caused by pulling, vibration, or flexing. This connector accommodates cable diameters from 0.310 to 0.560 inches, offering versatility for a wide range of industrial applications. The captive O-ring seal and steel locknut ensure a watertight and dust-tight connection that meets UL 514B standards for liquidtight fittings. With a compact design measuring 2.063 inches in length and 0.630 inches in thread diameter, the 2931SST fits efficiently in tight spaces while providing robust mechanical protection. Ideal for connecting flexible liquidtight Type A conduit to control panels, machinery, and enclosures, this connector is engineered for both indoor and outdoor installations where continuous or intermittent moisture exposure is expected. The straight configuration simplifies cable routing and installation, reducing labor time while ensuring long-term reliability in demanding operational conditions.
