Product Information
Full details
This ELECTRAPICK Heat Shrink Wire Connector Butt Terminals Kit is designed for DIY enthusiasts, automotive mechanics, and electrical contractors needing reliable wire connections. Its key benefit is creating secure, watertight, and corrosion-resistant splices with a simple heat application. A potential caveat is the need for a heat source, which must be managed carefully to avoid damaging the tubing. The kit includes 200 connectors in yellow, blue, and red, catering to various wire gauges (AWG 22-10), and features premium tin-plated copper and dual-layer polyolefin tubing for excellent conductivity and durability.

FAQs
What is the primary benefit of using heat shrink connectors?
Heat shrink connectors provide a secure, insulated, and watertight connection that protects against corrosion, moisture, and dust, which is especially beneficial in harsh environments like automotive and marine applications.
What tools are required to use these connectors?
You will need a wire stripper, a crimping tool, and a heat source such as a heat gun or a lighter.
How do I know which color connector to use?
The connectors are color-coded by wire gauge: Red for 22-18 AWG, Blue for 16-14 AWG, and Yellow for 12-10 AWG.
Can I use a regular lighter to shrink these connectors?
Yes, a lighter can be used, but it's important to keep the flame moving constantly to avoid scorching or melting the tubing unevenly. A heat gun provides more controlled and consistent heat.
What makes these connectors 'dual-layer'?
The dual-layer design refers to the polyolefin tubing exterior and the meltable adhesive lining on the interior. The tubing shrinks to provide insulation and mechanical protection, while the adhesive melts to create a watertight seal around the wires.
Are these connectors suitable for high vibration environments?
Yes, the combination of a secure crimp and the sealed, adhered connection provides good resistance to vibration.
How should I store unused connectors?
Store unused connectors in a cool, dry place, away from direct sunlight and extreme temperatures, to maintain the integrity of the adhesive lining.
Troubleshooting
Connector does not shrink properly.
Ensure you are using sufficient heat. Increase the temperature or duration of heat application, but be careful not to overheat or scorch the tubing. Verify that the connector is the correct size for the wire.
Adhesive is not sealing the connection.
The connection may not have reached the required temperature for the adhesive to melt. Apply heat more directly and evenly, focusing on the center of the barrel where the wires meet. Ensure the wire ends are stripped to the correct length and inserted fully.
Wires pull out after crimping.
The crimp was not strong enough. Use a quality crimping tool and ensure you apply adequate pressure to the connector barrel to secure both wires firmly before applying heat.
Tubing appears brittle or burnt.
Overheating has occurred. Reduce the heat intensity or the duration of exposure. Move the heat source continuously over the connector during the shrinking process.
Pros and Cons
Pros
- Provides a secure, insulated, and waterproof connection.
- Durable materials ensure long-lasting performance.
- Color-coding simplifies wire gauge identification.
- Easy to use with a standard heat gun or lighter.
- Excellent for preventing corrosion in harsh environments.
Cons
- Requires a heat source (heat gun, lighter) for activation.
- Overheating can damage the tubing or wires.
- Not suitable for very high-voltage or high-temperature applications without further assessment.
- Crimping tool is necessary for a secure mechanical connection before heating.
Setup, Compatibility & Care
Setup:
- Strip the insulation from the ends of the two wires you wish to connect.
- Insert one stripped wire end into one side of the butt connector.
- Insert the other stripped wire end into the other side of the butt connector.
- Using a crimping tool, firmly crimp the metal barrel of the connector around both wires. Ensure a secure mechanical grip.
- Apply heat evenly to the connector using a heat gun on a low-to-medium setting or a lighter (keeping the flame moving to avoid scorching). Heat until the tubing shrinks tightly around the wires and the adhesive inside melts and flows, creating a seal.
Compatibility:
This kit is compatible with standard wire gauges: Red (22-18 AWG), Blue (16-14 AWG), and Yellow (12-10 AWG). Ensure the wire gauge matches the connector size for optimal performance.
Care:
Store connectors in a dry place away from extreme temperatures and direct sunlight. Ensure the original packaging or a suitable container is used to prevent contamination or damage to the adhesive lining.
