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 and gland in glass-filled thermoplastic (blue), with an integrated neoprene O-ring for watertight sealing and a matching non-metallic locknut (black) for secure installation without metal contact. Designed for use with 3/4" liquid-tight flexible non-metallic Type A conduit (LFNC-A), it ensures reliable protection against moisture, dust, oils, cutting fluids, and mild acids 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. Typical applications include industrial machinery wiring, outdoor lighting installations, HVAC systems, and commercial electrical setups requiring liquid-tight protection. The fitting meets UL 514B standards for liquid-tight fittings and is suitable for electrical circuits up to 1000V. It provides ingress protection ratings of IP66, IP67, and IP69 per IEC 60529, with UL Listed Type 4, 4X, and 12 ratings. The O-ring ensures a consistent seal across a range of temperatures, while the locknut provides a firm grip without damaging the conduit.
