Waterproof Wire Connectors, Solder Sleeves, and Splice Kits

In harsh industrial environments, it is often essential for devices to withstand moisture. Water exposure can disrupt critical signals, corrode contacts, or damage equipment.

These waterproof splice connectors help prevent this by creating a seal that protects against dust, dirt, and short-term submersion. They encapsulate bare wires in an easy-to-use device. Heat the solder sleeve and dual-wall polyolefin adhesive-lined heat shrink with a hot gun until the glue flows.

Waterproof Wire Nuts

Waterproof wire connectors keep out moisture and prevent corrosion at exposed ends of electrical wiring. They are easy to install and typically require no special tools. They work well with both stranded and solid copper wires, making them ideal for landscape lighting. Some types of waterproof wire connectors feature a pigtail that extends from the top to provide extra length for connections.

There are many different kinds of waterproof wire connectors, including twist-on wire connectors (which make reversible connections that can be untwisted in the future), push-in wire connectors, and gel-filled connectors that seal out moisture. These waterproof electrical connectors also come in a variety of sizes, so you can choose the right one for your project.

Some types of waterproof wire connectors, such as those with a plastic outer shell, are filled with grease to protect against vibration that could loosen the connection. Others are filled with a dielectric silicone that keeps out moisture and oxidation.

Some of the best waterproof electrical connectors are made with a nylon body with gasketed end caps that are IP68 rated for use in harsh environments. They are easy to install: just insert the wire and waterproof splice connectors tighten the screw with a wrench. Some of these connectors are self-fusing, which means that the silicon inside of the sleeve will melt and bond with itself when you apply heat. Other waterproof electrical connectors are crimped and soldered, which requires the help of a soldering tool or a hot-melt glue gun.

Waterproof Solder Sleeves

Solder sleeves are a great alternative to crimp connectors for creating waterproof connections. They make it easy to join and splice wires in a variety of applications, including underground work. They are also a good choice for working in tight spaces. They’re easy to use and have a wide range of sizes to accommodate different wire gauges and materials. These sleeves are designed to withstand harsh environments, so you can be confident that your connection will be strong and reliable.

To use, simply strip the insulation off the ends of the wire you want to splice. Then, slide the ends of the wire into one end of a solder sleeve. Make sure the tinned ends are inside the solder rings. Then, heat the sleeve using a heat gun until the solder flows and makes a solid connection. After the solder has flown, apply a piece of polyolefin adhesive-lined heat shrink to protect your splice from moisture and debris.

These waterproof solder seal splice connectors are the perfect solution for wiring projects that require waterproof connections in hard-to-reach spaces. They’re abrasion-resistant and can withstand burial in rocky soil, plus they have an IP68 rating to keep out dust, dirt, and water even when briefly submerged. They have a durable nylon body with gasketed end caps and are simple to install—just twist the cap shut.

Waterproof Connectors

Waterproof connectors are a necessity in harsh environments, safeguarding electrical connections from moisture and other contaminants that can cause failures. With their versatile design and durable materials, they’re used in automotive electronics, outdoor lighting installations, industrial machinery, and other applications where connections are subject to extreme temperatures, moisture, dirt, and chemicals. By safeguarding these critical components, waterproof connectors reduce downtime and repair costs for businesses.

Corrosion and oxidation can damage custom cable assemblies and connectors, reducing the number of mating cycles they can handle. This can affect the longevity of your projects, making them less efficient and costlier to maintain over time. With the right tools and supplies, you can protect your cables and connectors from moisture-related damage.

Use waterproof solder sleeves to make quick connections while retaining insulation. These sleeves pierce the insulation without stripping it and seal tightly around the wire to keep out water and other elements. They’re available waterproof ethernet connector in 2-, 3-, or 4-wire splice configurations with termination buttons on each end to connect each wire independently. Choose from a variety of colors and wire gauges to easily match the right sleeve to each wire.

Waterproof overmolded circular connectors are a great choice for harsh industrial environments with high humidity levels and heavy dust. They’re made from sturdy materials and have a high IP rating to resist moisture ingress. They’re also designed for fast, hassle-free installation with features like snap-lock or screw-lock mechanisms.

Waterproof Splice Kits

Waterproof splice kits allow you to create gastight, waterproof connections without the need for potting compounds or molds. They’re ideal for applications that are often exposed to water or the elements like motor leads and power cables.

3M splice kits feature a plastic sleeve that’s positioned over the connection point to insulate and seal it. Liquid epoxy is then poured into it to completely encapsulate the cable and create a permanent, long-lasting connection. This splice kit is UL Listed and RoHS 2011/65/EU compliant.

This waterproof splice kit has everything you need to connect and extend fountain or aerator wires. It features 4 splice connectors and 4 clear dual wall heat shrink tubing that’s specifically formulated for groundwater. Heat is applied to the tubing and it quickly shrinks to a skin tight fit, forcing the melted adhesive to flow around the wires. Once cooled, it forms a durable and flexible waterproof seal.

The kit includes a plastic housing with screw terminals that you can mount to your project. It also has a lid with an O-ring that’s designed to resist water. It’s depth rated to 500 meters so it’s ideal for splicing power cables used in underwater applications such as in a submersible pump or aerator. This kit comes with an instructional manual to help you get started.
