Waterproof Splice Connectors

Waterproof splice connectors help you safely extend sensors and other equipment in the field. They snap together and enclose a solder sleeve and screw terminal, creating a waterproof connection that resists corrosion.

A dual-walled polyolefin heat shrink tube with hot-melt adhesive lines the splice to seal out moisture and debris. These revolutionary connectors are easy to use and require no crimping.

Twist-to-Connect Splices

If you’re working on electrical projects in your home, you’re likely to splice circuit wires. Ideally, you’ll run a single, uninterrupted cable from the service panel to each device and splice only when necessary. This reduces the possibility of severed wires in an emergency, makes for a neater wall and ceiling appearance, and eliminates confusion over which wire goes where. However, this isn’t always possible or practical. For example, you may need to connect two separate runs of wire or extend the length of a current run with a new piece of wire.

To splice wires, you have several options including soldering and crimping. Soldering involves melting and cooling a tin alloy onto the ends of the wires to create an effective connection. However, this method is time-consuming and requires specialized tools. It also exposes the metal to oxidization, which can cause performance issues over time. Crimping, on the other hand, provides a mechanically strong joint that resists vibrations and weather conditions. It requires the use of a crimping tool that resembles a pair of pliers and compresses the ends of the wire to form an electrically and physically robust joint.

Whichever splicing technique you choose, it’s important that you follow all applicable regulations and safety practices. For example, a soldered or twisted splice should be covered with heat-shrink tubing to insulate the joint from moisture, chemicals, and other environmental elements. It’s also essential to use UL-approved wire connectors like the familiar twist-on wire nuts or newer push-fit types, and always splice in an approved junction or fixture box.

Splices with Termination Buttons

With these one-step connectors, you can extend sensors and other outdoor equipment without splicing or cutting. The two halves filled with insulating silicone snap together to completely encapsulate bare wires and close all entryways against moisture. waterproof splice connectors A double O-ring seal bars water from creeping in, and latches lock the connector around the wires to prevent corrosion or tampering.

The splice connectors are color-coded for easy identification and are designed to be used with specific wire gauges to ensure they fit properly. They also feature a handy guide on the box that lists common wire gauges and colors to make finding the right connector easier.

Pierce insulation without stripping it and solder the tinned ends of the wires into the splice connectors’ built-in solder rings. Then, slide the outer heat shrink tubing over the splice connector and apply heat using a heat gun until the adhesive-lined heat shrink fuses tightly to the cable and splice connector. The resulting waterproof splice is sealed to keep out moisture, dust, and other contaminants and has a rugged nylon body that can handle repeated use.

Splices for Underground Applications

Make quick, watertight connections for underground applications without crimping. These splice connectors are pre-filled with silicone that fully encapsulates bare wire and closes all entryways to seal out moisture. An O-ring on each end bars ingress of water and prevents corrosion, and latches lock the connector around the wires to keep them in place. These splices are abrasion-resistant and can handle burial in rocky soil. They also come with a length of heavy-wall polyolefin adhesive-lined heat shrink to cover the splice and protect it from environmental conditions.

These splices are designed for fast, easy field installation of sensor cables and other wiring in harsh environments. They have termination buttons on both ends for independent connections, and they are color-coded to match wire gauges. They are IP68 rated to seal out dust and water, even if they are briefly submerged.

Use these waterproof splices to connect wires in a wide range of industries and outdoor applications, from paper mills waterproof ethernet connector to marine environments. They can withstand temperatures up to 150°F, and they feature multiple terminals for repairs or reconfiguration.

Splices for Indoor Applications

If you need to connect wires within a building or other structure, use these waterproof splice connectors. They have termination buttons on both ends so you can make independent connections on each side. These insulated butt connectors come in different sizes to match your wiring and have colored insulator jackets that correspond with their corresponding wire gauges. They also have a small slit to pierce the sheath and expose the wires for fast connections without stripping them.

Easily solder and seal your wires without needing tape using these waterproof splice connectors that have an inspection window. They are rated IP67 for dust and water resistance, making them suitable for use in most indoor environments. They also have a low-temperature solder sleeve for added safety and dual-walled insulation to prevent burns.

These wire connectors have thick threads that take only a few turns to lock into place for a secure connection in washdown or high-vibration locations. They’re also compatible with a wide range of devices, including sensors, switches, and other electrical components. They can even be used to transfer data at high-speed between PCs and PLCs. They tightly thread to M12 connections and won’t let contaminants in or loosen from vibration in rugged industrial environments or automated systems. They’re also tin-plated for resistance to corrosion. These cords meet UL standards for use in wet areas and can resist moisture and impact from rodents.
