Ancor's heat shrink butt connectors are a top - notch solution. This 25 - piece pack includes step - down connectors in sizes 22 - 18/22 - 14 (Model: 320125). The tubing has a 4:1 shrink ratio, creating a watertight seal between wires. The flared barrel with a uniform copper wall allows for an easy and proper mechanical crimp. There's a crimp indicator on the barrel for correct tool placement. The clear heat shrink tubing ensures accurate crimping. Colored stripes on the barrel show which crimp die to use, no matter the application. These connectors can step down from one gauge size to another or serve as multi - wire connectors for single - gauge wires. They're a sealed alternative to quick - taps or 3 - way connectors in corrosion - prone areas.

Using these Ancor heat shrink butt connectors is easy. First, select the right connector according to the wire gauge. The colored stripes on the barrel will help you choose the correct crimp die. Place the wires into the connector barrel. Make sure to position the installation tool at the crimp indicator on the barrel for a proper crimp. Once the wires are in place and the tool is set, apply pressure to crimp the connector onto the wires. After crimping, use a heat source like a heat gun to shrink the tubing. Keep the heat source moving evenly around the tubing to ensure a 4:1 shrink ratio and a watertight seal. When it comes to maintenance, check the connectors periodically for any signs of damage or loosening. If you notice the seal is compromised, replace the connector. Also, store the connectors in a dry place to prevent corrosion. Avoid using excessive force when crimping as it might damage the connector or the wires.
