Overview

The ABB Installation Products 6303NM 3/4" Straight Non-metallic Liquid-tight Type A Fitting provides a secure, corrosion-resistant connection for liquid-tight conduit systems. This fitting features a non-metallic body with an integrated O-ring for watertight sealing and a matching non-metallic locknut for secure installation without metal contact. Designed for use with 3/4" liquid-tight flexible conduit, it ensures reliable protection against moisture, dust, and contaminants in indoor and outdoor applications. The non-metallic construction resists corrosion and chemical exposure, making it ideal for harsh environments where metal fittings may degrade. Common applications include industrial machinery wiring, outdoor lighting installations, HVAC systems, and commercial electrical setups requiring liquid-tight protection. The fitting meets Type A liquid-tight standards, ensuring compliance with NEC and other electrical codes for conduit sealing. No metal components contact the conduit, reducing the risk of galvanic corrosion. The O-ring provides a consistent seal across a range of temperatures, while the locknut ensures a firm grip without damaging the conduit. This fitting is part of ABB’s Installation Products line, known for reliable electrical components. SKU 6303NM is a direct replacement for standard liquid-tight fittings in existing systems.
  • 3/4" straight non-metallic liquid-tight fitting
  • Integrated O-ring for watertight sealing
  • Non-metallic locknut for corrosion-free installation
  • Type A liquid-tight compliance for NEC and code adherence
  • Suitable for indoor/outdoor industrial, HVAC, and lighting applications
