Heat Shrink Butt Connector, 16-14 AWG, Blue, 5-Pack

The E-CON-HS4mm is a heat shrink butt connector crimp terminal designed for joining and insulating wire splices in electrical and low-voltage applications. It is sized for 16-14 AWG conductors and features a 4.0mm outer diameter with a 15mm length, making it suitable for compact wiring enclosures and tight installation spaces. The connector uses a crimp-and-shrink design: the terminal is crimped onto stripped wire ends, then heat is applied to shrink the sleeve, sealing the joint against moisture and corrosion while providing strain relief. The blue color coding identifies the 16-14 AWG size range for quick selection during installation or repair work. Each package contains 5 pieces, and the connector carries a 1-year warranty.
