PIONEERING INDUSTRY STANDARDS SINCE THE EARLY 1900S
T&B Fittings established the benchmarks that define modern conduit installation. As part of Thomas & Betts' legacy of electrical innovation, T&B Fittings introduced products that became industry standards - many still bearing the original registered trademarks today.
Industry standards such as Chase nipples, Erickson couplings, and liquid-tight fittings were introduced by T&B and remain registered trademarks today. These innovations transformed conduit installation by solving real-world contractor challenges with engineered solutions that simplified connections, improved reliability, and accelerated project timelines. What started as problem-solving innovations became the standard specifications written into electrical codes and contractor practices across North America and beyond.
This legacy of innovation continues with comprehensive solutions for electrical metallic tubing (EMT), rigid conduit, intermediate metallic conduit (IMC), and liquid-tight flexible conduit systems - all engineered for reliable connections and code compliance. Today, as part of ABB Installation Products division, T&B Fittings combines over a century of proven performance with modern manufacturing excellence and global technical support. From residential construction to industrial facilities, T&B Fittings remains the trusted choice for electrical professionals who demand quality, reliability, and innovation in every connection.
