Ancor's 25-piece heat shrink butt connectors are step-down connectors for 24-22/24-18 wires. Model 320025 features a 4:1 shrink ratio tubing for a watertight wire seal. The flared barrel with uniform copper wall allows for easy and proper mechanical crimping. There's a crimp indicator on the barrel for correct tool placement, and clear heat shrink tubing ensures crimp accuracy. Colored stripes on the barrel show which crimp die to use. These connectors can step down from one gauge size or connect multiple wires of the same gauge, offering a sealed option for areas prone to corrosion, better than quick-taps or 3-way connectors.

Using these Ancor heat shrink butt connectors is a breeze. First, select the right connector according to the wire gauge and the colored stripes on the barrel. Place the wires into the connector barrel. Make sure the crimp indicator on the barrel aligns with your installation tool for proper placement. Then, use the correct crimp die as indicated by the colored stripes to crimp the connector onto the wires. After that, apply heat to the heat shrink tubing. The 4:1 shrink ratio tubing will shrink and create a watertight seal. As for maintenance, keep the connectors dry to prevent corrosion. If you notice any signs of damage or poor connection, replace the connector. And always store them in a cool, dry place when not in use.
