Corning UY2-D Unfilled IDC Butt Splice Connector for 2-3 Conductors, 22-26 AWG, 120-Pack 80610578272

The Corning UY2-D stands out as a compact, unfilled insulation displacement connector designed for quick, reliable splicing of 2 or 3 solid copper conductors without stripping or soldering. Its transparent polypropylene body allows visual confirmation of conductor placement, while the tin-plated brass contact element ensures a gas-tight connection. Supplied in a carton of 120 pieces, it is a practical choice for high-volume telecommunications and signal wiring tasks.

Highlights

• Accommodates 2 or 3 conductors from 22 to 26 AWG (0.4–0.9 mm)
• Unfilled design – no gel or sealant, ideal for dry indoor environments
• Clear body with red cap for easy identification and inspection
• Rated for 600 V and temperatures from -40°C to 75°C
• Compatible with standard IDC crimp tools such as the 3M E-9Y

In daily use

Installers appreciate the UY2-D for its speed and consistency. Insert unstripped wires into the ports, squeeze with a proper crimping tool, and the contact element displaces insulation to create a secure, low-resistance splice. The transparent housing lets you verify that wires are fully seated before crimping. Because it is unfilled, it is best suited for indoor applications where moisture protection is not required.
