Overview

The ABB TX 221 Combination Set-Screw Coupling (SKU: TX 221) is a precision-engineered connector designed to join 1/2 inch flexible metal conduit to 1/2 inch Electrical Metallic Tubing (EMT). Constructed from die-cast zinc, this coupling ensures superior mechanical strength and corrosion resistance, making it ideal for demanding industrial and commercial electrical systems. The set-screw design delivers a vibration-resistant connection, critical for maintaining circuit integrity in high-stress environments such as panel wiring, machine installations, and building infrastructure. Measuring 1-13/16 inches in length and 1-5/32 inches in width, the TX 221 is engineered to fit standard conduit systems without modification. Its compact dimensions and robust construction simplify installation by eliminating the need for separate adapters or reducers. The coupling is UL File No. Key applications include: - Panel wiring and control systems - Machine installations requiring secure conduit transitions - Industrial environments with high vibration or mechanical stress Compatible with common 1/2 inch conduit sizes, the TX 221 provides a reliable, long-term solution for conduit transitions in both new installations and retrofit projects. Its die-cast zinc construction and set-screw mechanism ensure a tight, secure fit that resists loosening over time, reducing maintenance requirements and improving system reliability.
