Overview

The ABB UNY205-B PVC Coated Explosion and Dust-Ignition Proof UNY Male Union (SKU: UNY205-B) is a UL 1203 and CSA C22.2 No. 25/30 certified three-piece coupling designed for hazardous and non-hazardous locations. Engineered for rigid conduit systems, this union connects threaded conduit to fittings, junction boxes, or enclosures in Class I, Division 1 & 2 (Groups A, B, C, D), Class II, Division 1 & 2 (Groups E, F, G), and Class III environments. The electrogalvanized steel body ensures structural integrity, while the double-coat PVC/urethane finish (0.040" PVC exterior, 0.002" blue urethane interior) delivers corrosion resistance, UV stability, and grounding continuity. With a 3/4-inch NPT pipe size, 2.44-inch overall length, and 1.81-inch diameter, the UNY205-B fits compact spaces without compromising durability. The light blue color enhances visibility for quick identification in industrial settings. Ideal for oil and gas, chemical processing, manufacturing, and wastewater facilities, this union meets NEC/CEC and NEMA standards for explosionproof and dust-ignitionproof applications. Compatible with rigid conduit systems in wet, corrosive, or hazardous locations.
