Overview

The ABB 3741 1/2" Steel Type A 90° Liquidtight Connector (SKU: 3741) delivers a secure, liquid-tight connection for Type A non-metallic flexible conduit in industrial and commercial environments. Engineered for durability, this connector features a zinc-plated steel body with a nylon-insulated throat to protect wire insulation from abrasion and damage. The 90-degree design enables efficient conduit routing in tight spaces or where directional changes are required, reducing installation complexity and minimizing bend radii. A Santoprene® sealing gasket combined with a Type 316 stainless steel retaining ring ensures a positive seal against water, oil, dust, and other contaminants, maintaining electrical integrity in harsh or wet conditions. The integrated Neoprene O-ring and steel locknut provide additional mechanical stability and pull-out resistance, preventing accidental disconnection during operation. The NPT hub threads create a secure, threaded connection to female threads, while the captive sealing ring simplifies installation and ensures consistent performance. With a compact design measuring 1⅜" (A) x 2⅛" (B) and weighing approximately 0.38 lbs, the 3741 is optimized for space-constrained applications without compromising reliability. Suitable for continuous or intermittent moisture exposure, this connector meets NEC® Article 356 requirements for flexible, liquidtight non-metallic conduit systems.
