Clamp-On No-Crimp Butt Splices
Press down on the clamp to connect wires for quick field installation, no crimping or tools required. These splices disconnect as easily as they connect and are reusable, making them good for testing or prototyping setups that frequently change.
These splices create a secure hold, so they’re often used in electrical enclosures such as outlet boxes. They’re clear, which allows you to visually confirm wires are properly connected. To mount them in control cabinets, use splice holders and DIN-rail adapters (both sold separately).
Splice holders have a flange that slides into the groove of another holder, so you can connect multiple holders together. Screw-on holders are more secure than snap-on holders. Snap-on holders are a good choice if you’re attaching multiple holders to a DIN rail because they’re quick to install.
DIN-rail adapters clip onto DIN rail.
Covers have an inner gel that seals splices to keep out water, dust, and debris. Unlike potting compounds, covers don’t require mixing or pouring to install. If you need to expand or repair a circuit, you can open these covers and reuse the wires inside. However, once you open a cover and remove the gel, you’ll need a new splice and cover.

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.

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.
