Thomas & Betts 8221 3/4" Threadless Rigid Conduit Connector

The Thomas & Betts 8221 is a 3/4" threadless rigid conduit connector designed to deliver a fast, secure mechanical connection between rigid metal conduit (RGD) and electrical enclosures, boxes, or panels. Unlike traditional threaded fittings, the 8221's threadless design allows installers to make up the connection without cutting or chasing threads in the field, saving time on every joint. Sized to the 3/4" trade size, this connector is built to work seamlessly with standard 3/4" rigid conduit runs commonly found in commercial, industrial, and institutional electrical systems. Electrical contractors rely on connectors like the 8221 to maintain a solid mechanical connection at every conduit termination point, helping the overall raceway system perform as intended from installation through the life of the system.

Key Features

  • Trade Size: The 3/4" trade size matches standard 3/4" rigid metal conduit (RGD), ensuring proper fit and alignment at the connection point.
  • Threadless Design: The connector's threadless configuration eliminates the need for field threading tools, reducing labor time and simplifying installation on rigid conduit runs.
  • Rigid Conduit Compatibility: Purpose-built for rigid metal conduit (RMC/RGD) systems, the 8221 is engineered to provide a dependable mechanical connection between conduit and equipment.
  • Secure Connector Type: Designed to join conduit runs to enclosures, junction boxes, and panels, helping maintain a continuous, protected raceway pathway for conductors.
  • Model 8221: Identified by Thomas & Betts model number 8221 within the broader rigid conduit fitting lineup, making it easy to specify and reorder for future projects.
  • Field-Ready Installation: The threadless connection method is intended to speed up rough-in work where multiple conduit-to-box connections must be made efficiently.
