Solder-Loaded Noninsulated No-Crimp Butt Splices

Create a secure wire connection that stands up to both water and high temperatures without any crimping. These splices have enclosed solder that melts when heated, filling the gap between wire strands to bond the wires together and create a watertight seal. This connection is more reliable than a crimp-on connection. These splices don’t have plastic insulation, so they withstand ovens, motors, and other high-heat applications. Use a heat gun or butane torch to melt the solder.

Multi-Way Taps/Splices





Tap and splice multiple wires together at the same time. Insert your main wire into a port and each tap wire into the other ports before tightening the screws. All are fully insulated with PVC. UL listed, they meet U.S. safety standards.
For splices with through holes, one side of each port must remain open.
Splices with plastic plugs cover the screw openings to keep contaminants out. Splices with through holes and plastic plugs let you close entry ports that aren’t in use.
Use black, blue, and clear splices with Class B and C stranded wires. Clear splices help you confirm the connection visually.
Use gray splices with Class B, C, and D stranded wires.
Splices that are C-UL listed meet Canadian safety standards.
