Weatherproof Solderless Heat Shrink Tubing Connector For RGB Flexible LED Light Strips, 10cm by sale$0.50
Product Information
Ensure your electrical connections are secure and completely protected from the elements with our Waterproof Heat Shrink Butt Connectors. Sold in a convenient 3-pack, these insulated terminals are the professional choice for creating reliable, moisture-proof wire-to-wire splices. The heat-activated adhesive lining melts to form a complete environmental seal, safeguarding your wiring against water, salt, and corrosion. These splice electrical connectors are an essential accessory for creating durable, weather-resistant connections, especially when extending cables for an AC waterproof plug or linking to our range of waterproof power supplies. Available in sizes to fit 16-22 AWG wire, they are perfect for a wide range of low-voltage applications.
Key Features
Superior Weatherproofing
A heat-activated adhesive lining melts and flows to create a complete, impenetrable waterproof seal around the wire.
Versatile Wire Compatibility
Available in two sizes to accommodate a wide range of common wire gauges, from 16 AWG down to 22 AWG.
Durable Protection
The tough, insulated vinyl terminal protects the wire splice from water, salt, corrosion, and physical abrasion.
Secure Crimp Connection
Provides a strong, permanent crimp for excellent conductivity and tensile strength before the heat-sealing process.

Application Scenarios
How to Use These Waterproof Butt Connectors
- Select the correct connector size for your wire gauge (16-20 AWG or 20-22 AWG).
- Strip approximately 1/4 inch (6-7mm) of insulation from the ends of the two wires you wish to connect.
- Insert one stripped wire end into one side of the butt connector until it hits the center stop. Crimp firmly using a standard wire crimper.
- Insert the second wire into the other end and crimp it securely.
- Gently tug on both wires to ensure a solid mechanical connection has been made.
- Using a heat gun, apply heat evenly to the connector, rotating the wire. Start from the center and work outwards.
- Continue applying heat until the tubing shrinks down and the adhesive flows out of the ends, creating a visible waterproof seal.
- Do not overheat the connector, as this can damage the vinyl insulation.
- A heat gun is strongly recommended over an open flame for even heat distribution and a reliable seal.
- Allow the connector to cool completely before handling or putting any strain on the connection.
- Ensure you are using a proper crimping tool to achieve a secure electrical bond before sealing.

Frequently Asked Questions
Q: What tools do I need to use these butt connectors?
A:You will need a wire stripper to remove insulation, a crimping tool to secure the wire, and a heat gun to shrink the tubing and activate the waterproof adhesive.
Q: Are these connectors reusable?
A:No, these are single-use connectors. The crimping and heat-sealing process creates a permanent, non-removable splice.
Q: Can I use a lighter instead of a heat gun?
A:A heat gun is highly recommended for even heat distribution and a reliable seal. Using a lighter can easily scorch the insulation, leading to an incomplete seal and a weaker connection.
Q: What is the difference between the 16-20 AWG and 20-22 AWG sizes?
A:The sizes correspond to the American Wire Gauge (AWG) of your wire. Use the 16-20 AWG connector for thicker wires and the 20-22 AWG for thinner wires within those specified ranges for a proper fit and seal.
Q: Are these suitable for high-voltage AC house wiring?
A:These connectors are primarily designed for low-voltage DC applications, such as LED lighting, automotive, and marine wiring. Always consult your local electrical codes for high-voltage applications.
Q: How do I know when the seal is fully waterproof?
A:When properly heated, you will see the tubing shrink tightly around the wire and a ring of clear adhesive sealant will become visible as it flows from both ends of the connector.
