Noninsulated Reducing Crimp-On Butt Splices

These splices can withstand higher temperatures than insulated splices. Use them to connect two wires of different sizes—one end of the splice is larger than the other. They have a colored stripe on the smaller end.
For Wire Gauge | Lg. | Color | Terminal Material | Max. Temperature, °F | Specifications Met | Pkg. Qty. | Pkg. | |

Insulated Reducing Crimp-On Butt Splices

A plastic cover fully insulates these splices. Use them to connect two wires of different sizes—one end of the splice is larger than the other. They are color-coded according to the larger wire gauge size and have a colored stripe to indicate the size of the smaller end.

Heat-Shrink Reducing Crimp-On Butt Splices

When heat is applied, adhesive-lined insulation shrinks and bonds to the wires, creating a watertight seal. Use these splices to connect two wires of different sizes—one end of the splice is larger than the other. They are color-coded according to the larger wire gauge size and have a colored stripe to indicate the size of the smaller end.

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.
