Overview

The ABB NPL4X4-G is a high-performance PVC-coated conduit nipple engineered for rigorous industrial and commercial electrical installations. This nipple is manufactured from hot-dip galvanized rigid steel, ensuring exceptional mechanical strength and long-term corrosion resistance against environmental stressors. The product features a 4-inch nominal pipe size (NPS) with a corresponding 103mm metric equivalent, paired with a 4-inch (101.6mm) nipple length, providing standardized compatibility with standard conduit systems. Internally, the nipple is coated with a nominal 0.002-inch (2 mil) layer of blue urethane, which facilitates smooth wire pulling by reducing friction and minimizes the risk of insulation damage during installation. The exterior is protected by a minimum 0.040-inch (40 mil) PVC coating, offering robust defense against abrasion, moisture ingress, chemical exposure, and other corrosive elements commonly encountered in industrial settings. The threads are additionally reinforced with a blue urethane coating, preserving thread integrity, preventing galling, and ensuring reliable, leak-tight connections when mated with other conduit components. Designed for durability in harsh environments, the NPL4X4-G maintains electrical system integrity by preventing moisture ingress and corrosion within the conduit run. Its dark gray (G) color provides visual identification and is compliant with NEMA RN 1 standards for PVC coating thickness and continuity, guaranteeing consistent performance and protection. This nipple is an ideal solution for applications in chemical plants, refineries, wastewater treatment facilities, and other demanding environments where conduit protection is critical. Trust ABB Installation Products for a conduit nipple that delivers uncompromising reliability and extended service life in the most challenging conditions.
