Metra Electronics HSYBC

The Metra Electronics (The Install Bay) HSYBC is a professional-grade pack of Heat Shrink Yellow Butt Connectors (12–10 AWG). Engineered for automotive, marine, powersports, and general 12-volt wiring applications, these connectors provide a sealed, moisture-proof wire splice with built-in strain relief.

Key Features

• Adhesive-Lined Heat Shrink: Features an internal heat-activated adhesive that melts and flows when heated, creating a waterproof, corrosion-resistant seal against moisture, dirt, and chemicals.

• High Conductivity: Built with an internal copper barrel crimp sleeve to ensure maximum current flow and low electrical resistance.

• Strain Relief & Vibration Resistance: The dual-wall polyolefin shrink tubing grips the wire insulation to resist pull-out, tension, and continuous vehicle vibration.

• Industry Standard Color Coding: Coded yellow to signify compatibility with standard 12 AWG to 10 AWG wiring.
