Adhesive lined heat shrink butt connectors can be used as a step-down from one gauge size to another or as a multi-wire connector for one gauge size wire. These connectors offer a sealed alternative to products such as a quick-tap or 3-way connector in areas where corrosion is a concern.4:1 shrink ratio tubing to ensure a watertight seal between wiresFlared barrel with uniform copper wall ensures an easy and proper mechanical crimpCrimp indicator on barrel for proper placement of installation toolClear heat shrink tubing ensures crimp accuracyColored stripes on the barrel indicate which crimp die to use, regardless of applicationTech Tip: Why Heat Shrink TerminalsHeat shrink terminals create a sealed connection between the terminal itself and the wire the connector is crimped to. Sealed connections prevent corrosion and provide additional strain relief for the connection. Corrosion reduces the carrying capacity of the electrical system and reduces the strength of the conductor. Over time, wire that is not sealed can degrade and break, leading to costly repairs.
