Overview

The ABB NPL4X12-G is a high-performance PVC-coated conduit nipple engineered for maximum corrosion resistance and electrical protection in demanding industrial, commercial, and utility applications. Constructed from hot-dip galvanized rigid steel, this nipple delivers superior mechanical strength and long-term durability, ensuring reliable performance in harsh environments. The interior is coated with a nominal 0.002-inch (2 mil) blue urethane layer, optimized for smooth wire pulling and enhanced protection against moisture, abrasion, and chemical exposure. The exterior features a minimum 0.040-inch (40 mil) PVC coating, providing a thick, resilient barrier against physical damage, corrosive agents, and environmental stressors such as UV exposure, extreme temperatures, and high humidity. Threads are additionally coated with blue urethane to prevent corrosion, ensure secure mechanical connections, and maintain electrical continuity. This 4-inch (103 metric size) by 12-inch (304.8 mm) nipple is designed for compatibility with standard 4-inch conduit systems, offering precise dimensional accuracy for seamless integration. The standard finish is a durable dark gray (G) PVC coating, though custom colors are available upon request to meet specific project requirements. The product meets ANSI C80.1 standards, ensuring compliance with industry regulations for conduit fittings. Manufactured in the US, the NPL4X12-G is ideal for applications requiring robust protection in corrosive or high-impact environments, including chemical processing plants, wastewater treatment facilities, power distribution systems, and outdoor utility installations. Its combination of galvanized steel core, dual-layer coating system, and precision threading makes it a reliable choice for critical infrastructure projects where long-term performance and corrosion resistance are essential.
