Solder-Loaded Heat-Shrink Crimp-On Butt Splices

The most secure, electrically conductive, and environmentally sealed connection we offer, these splices have enclosed solder and an adhesive-lined insulation that melt when heat is applied. The insulation shrinks and bonds to wire, protecting it from water and corrosion.

Solder-Loaded Heat-Shrink Reducing Crimp-On Butt Splices

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.

Solder-Loaded Heat-Shrink No-Crimp Butt Splices

With a ring of solder on the inside, these heat-shrink splices create secure, water-resistant connections between wires without the need for a crimping tool. Instead, heat the splice with a heat gun or butane torch to shrink the tubing, seal the connection, and liquefy the solder.
Because they use solder, these splices make more reliable connections than crimp-on splices. The melted solder fills the gaps between the wires' strands to make the electrical connection. Made of a tin-bismuth alloy, it's safe to use where lead is prohibited. It has a lower melting point than lead, so you're less likely to melt the heat-shrink tubing before melting the solder.
A layer of hot-melt adhesive lines the inside of the heat-shrink tubing to prevent the wires from pulling apart. The adhesive also seals the connection, blocking out water, dust, and other contaminants that can corrode the wire and cause a short.
To help with identification, each size has a different color. All are UL recognized for use with other components in an electrical system. When used with other UL recognized components, such as wires of the correct gauge, they can be part of a UL listed final product.
