Overview

The ABB NPL3/4X31/2-B PVC Coated Conduit Nipple is a corrosion-resistant, durable solution for industrial electrical installations requiring threaded conduit connections. This 3/4-inch pipe size nipple measures 3.5 inches (88.9 mm) in length and is manufactured from hot-dip galvanized rigid steel for superior strength and longevity in harsh environments. The interior features a nominal 0.002-inch (2 mil) blue urethane coating for chemical resistance and smooth wire pulling, while the exterior is protected by a minimum 0.040-inch (40 mil) PVC coating bonded to the steel substrate. Threads are coated with blue urethane for added durability during repeated installations. The light blue color provides easy identification during installation and maintenance, and the product is distributed by Gross Automation. Standard offerings include dark gray PVC coating (G), with light blue (B) as a custom option. This nipple is ideal for chemical plants, water treatment facilities, outdoor industrial settings, and other corrosive environments where reliable conduit protection is critical. Compatible with Ocal-Blue® double-coat split couplings for seamless integration into corrosion-resistant conduit systems.
