Check to make sure you’ve made a secure connection between two different sizes of wire with the inspection window on these splices. When heated, their adhesive-lined insulation shrinks and bonds to wires, creating a water- and corrosion-resistant seal. They have colored stripes to help differentiate end sizes, so you can easily match your wire to the right end.

Create a water- and corrosion-resistant seal while connecting two different sizes of wire. When these splices are heated, the solder inside melts and the adhesive liner shrinks and bonds to form the seal. Because of this seal, these splices are the most secure, electrically conductive splices we offer that connect two different sizes of wire. All have a stripe on the smaller end that’s a different color than the body, so you can easily match your wire to the right connector.
