Waterproof Splice Connectors

Waterproof splice connectors eliminate the need for time-consuming tape, heat shrink or mastics. They also offer a corrosion-resistant seal for use in damp, wet and partially submerged environments.

CoolSplice connectors are simple to install and use. No special tooling required; a common pair of pliers is used to pushbutton terminate insulated wires into an insulation displacement crimp contact.

Easy to Install

A waterproof splice connector provides a quick and easy solution for connecting wires, eliminating the need to use tape, heat shrink, or mastics. Simply place stripped wires inside the terminal and twist. Once complete, the one-step installation eliminates the need for messy tools and supplies, saving installers valuable time.

The splice connector’s silicone-filled cap completely encapsulates all bare wires and closes entryways to protect against moisture and corrosion. A double O-ring seal bars water from creeping in, and a latch locks the connector around the wires. It’s the perfect choice for sprinkler and landscape lighting wire splices, direct burial connections, trailer wiring, and more.

Rated IP68, CoolSplice is revolutionizing the way we splice cables for water-resistant applications. Using a revolutionary solder sleeve with dual-walled heat shrink tubing, this product provides a waterproof seal in a simple and user friendly design. Step 1 – Place wires inside the solder sleeve making sure the tinned ends are matched together (red-red, black-black). Step 2 – waterproof splice connectors Slide the heat-resistant tubing onto each end of the cable and splice connector, heat with a heat gun until the adhesive-lined heat shrink is fully melted and has an even appearance.

A quick and easy termination process makes CoolSplice a great alternative to soldering or splicing with copper tape. No special tooling is needed — a common pair of pliers is used to pushbutton terminate the insulated wires into an insulation displacement crimp contact. The connector is visually confirmed by the clear sidewall ensuring a solid, reliable connection.


As anyone who has ever worked on outdoor sensor installations can tell you, splice connectors often need to be sealed against the elements. This helps prevent water from corroding the splice and shorting it out. There are several different ways to seal a splice, and some of them work better than others.

One way to do this is to use silicone grease. This works well, but it can be messy to apply. Another option is to use a waterproof solder wire connector, which provides an extra layer of protection from the elements. These are available in a variety of sizes to accommodate many different types of wire, and they are designed to be easy to install and use.

The best waterproof wire connectors are made out of materials that make them resistant to moisture and other environmental contaminants. These include plastic and metal. They can also come with different Ingress Protection (IP) ratings to protect against specific environments, such as submersion and other harsh conditions.

Waterproof wire connectors are a great choice for irrigation or sprinkler wires, and they are also an excellent solution for repairs to trailers and other weather sensitive wiring. Some of these products feature double O-ring seals to bar water from getting in, and latches that lock tightly to keep the connector closed. Some even come with pre-filled silicone that encapsulates all of the bare wires, closing off entryways against moisture and corrosion.

Weather Resistant

Waterproof splice connectors prevent moisture ingress that could damage connections. This means that you can keep them protected for a long time, even when they are exposed to the elements. This is important in many electrical systems, including outdoor wires that could be in wet locations that might get submerged in the rain or mud, for instance.

There are several ways to make an electrical connection waterproof, including the use of a waterproof connection box, suitable silicone sealant or epoxy resin. The key is to ensure that you apply them properly and follow the instructions for each product.

Some splice connectors have an IP rating that indicates how well they are protected against water ingress and other environmental contaminants. Selecting the correct level of protection is critical to your system because it can prevent electrical issues that would disrupt data transmissions or corrode contacts, for example.

You can also choose a waterproof splice connector that has an insulation-displacement crimp contact to splice insulated and uninsulated wires together in one step. These are a great choice for applications that need to be environmentally sealed, such as underground wiring or solar panel installations. Gardner Bender Xtreme series terminals, for example, have an outer layer of adhesive-lined heat-shrink tubing that melts and seals the splice when heated, protecting them from wire pullout, corrosion, and moisture ingress.

Easy to Terminate

You can rely on waterproof splice connectors for easy and fast electrical connections. They replace time-consuming measures such as tape, mastics or corrosion kits. They also eliminate the need for crimping or soldering connections. They M12 waterproof connector come in different shapes, sizes and color-codes to match the specific needs of your project.

You can use insulated butt connectors to make an electrical connection between two wires in an end-on-end configuration. These connectors are designed to provide a compression type of connection that is suitable for both stranded and solid conductor cables. They can be used for a variety of applications including marine, automotive, commercial and residential wiring projects.

Another type of electrical terminal is a CoolSplice connector. This innovative technology provides a reliable way to terminate both stranded and solid copper wires without the need for tools. It is simple to use – all you need is a common pair of pliers.

If you’re looking for a waterproof solderable connector, you can opt for an adhesive-lined butt connector that requires no heat shrinking. These are suitable for high-temperature and low-voltage applications, making them ideal for industrial and commercial projects. They feature a dual-walled, hot-melt adhesive tubing that protects the cable from moisture. They are also tin plated for resistance to corrosion. They’re suitable for use in a wide range of copper cable sizes and are tamper-resistant.
