Overview

The ABB NPL3/4X41/2-B PVC Coated Conduit Nipple is a corrosion-resistant, threaded steel nipple designed for industrial electrical installations requiring durable conduit connections. Constructed from hot-dip galvanized rigid steel, this nipple features a nominal 0.002-inch (2 mil) blue urethane coating on the interior surface and a minimum 0.040-inch (40 mil) PVC coating on the exterior, providing exceptional resistance to moisture, chemicals, and abrasion. The threads are coated with blue urethane for added protection against thread wear and corrosion, ensuring long-term reliability in harsh environments. Measuring 3/4-inch pipe size by 4-1/2 inches in length, the NPL3/4X41/2-B is part of ABB’s Ocal-Blue® corrosion-resistant conduit system, optimized for applications where standard couplings cannot be used. The blue urethane interior coating prevents electrical interference and reduces friction during wire pulling, while the thick PVC exterior coating resists UV degradation, salt spray, and industrial contaminants. This product is ideal for chemical plants, water treatment facilities, food processing plants, and outdoor installations where corrosion is a critical concern. Available in standard and custom lengths, the NPL3/4X41/2-B is designed for quick field installations. The color-coded thread protectors (light blue for 3/4-inch size) enable easy identification and organization on job sites. Compatible with Ocal-Blue® double-coat split couplings, this nipple simplifies conduit assembly in tight spaces or where traditional coupling methods are impractical. Trust ABB Installation Products for a high-quality, dependable solution that meets UL and ANSI C80.1-1994 standards for conduit systems.
