Overview

The ABB NPL4X401/2-G PVC Coated Conduit Nipple is a corrosion-resistant, durable solution for industrial electrical installations requiring long-term performance in harsh environments. Constructed from hot-dip galvanized rigid steel, this nipple features a minimum 40 mil (0.040 inch) PVC coating on the exterior for superior protection against moisture, chemicals, and abrasion. The interior is coated with a nominal 2 mil (0.002 inch) blue urethane layer, ensuring smooth wire pulling and resistance to internal corrosion. Threads are protected with an additional blue urethane coating to prevent thread damage and ensure leak-proof connections. Designed for both indoor and outdoor applications, the NPL4X401/2-G is ideal for industrial, commercial, and utility settings where reliable electrical conduit connections are critical. The gray PVC exterior provides an additional layer of durability, while the blue urethane interior coating enhances longevity by resisting abrasion and chemical exposure. This nipple is compatible with standard rigid steel conduit systems and meets NEMA RN 1 standards for continuous PVC coating over the entire length, excluding threads. Key specifications include a 4-inch nominal pipe size (metric size 103) and a 40.5-inch (1,028.7 mm) length, making it suitable for a wide range of conduit runs. The product is distributed by Gross Automation and is manufactured in the US. Custom colors are available upon request, with standard offerings in dark gray. For installation, refer to ABB’s installation tooling and procedures for optimal performance and compliance.
