Overview

The ABB CPL21/2SST is a 2-1/2 inch Type 316 stainless steel conduit coupling designed for industrial applications requiring high corrosion resistance and durability. Type 316 stainless steel provides superior resistance to chlorides, acids, and other corrosive environments compared to standard 304 stainless steel, making it ideal for chemical processing, food and beverage, pharmaceutical, and marine applications. This coupling ensures a secure, leak-proof connection between two conduit sections, maintaining electrical system integrity in harsh conditions. The 2-1/2 inch size accommodates standard trade sizes for rigid metal conduit (RMC), intermediate metal conduit (IMC), and electrical metallic tubing (EMT) systems. Compatible with threaded conduit systems, the CPL21/2SST is manufactured by ABB Installation Products, a trusted name in electrical infrastructure solutions. The coupling’s stainless steel construction resists rust, oxidation, and pitting, extending service life in outdoor or chemically aggressive environments. It meets industry standards for mechanical strength and electrical continuity, ensuring reliable performance in demanding installations.
