Heat-Shrink Butt Connector Trytyt TTS-25 with Copper Sleeve, pack of 10

Heat-shrink butt connector Trytyt TTS-25 with copper sleeve, pack of 10 is designed for forming insulated, mechanically secure electrical splices in low-voltage wiring. The connector combines a copper sleeve for reliable electrical contact and a heat-shrink polyolefin tube that seals the joint against moisture, dust and mechanical strain. Supplied in a pack of ten, these connectors are suitable for repair and installation work in automotive, marine and general electrical applications where a sealed, durable joint is required.

Advantages

The copper sleeve provides consistent conductivity and a solid crimp point while the heat-shrink tubing ensures a tight, moisture-resistant seal after application. This combination reduces the risk of corrosion and improves mechanical stability of the splice. The connectors are compact and simple to apply with standard crimping and heat tools, enabling repeatable results and reliable insulation in confined spaces.

Suitable for

• Repairing and extending automotive wiring harnesses
• Marine electrical connections exposed to moisture
• General low-voltage household and industrial wiring repairs
• Installation of sensors, lights and auxiliary equipment

Key specifications

• Connector type: heat-shrink butt splice with copper sleeve
• Material: copper conductive sleeve, heat-shrink polyolefin tubing
• Application: low-voltage electrical splices
• Protection: provides moisture and strain relief when heat-shrunk
• Pack quantity: 10 pieces

How to use

Strip the wire insulation to the appropriate length, insert both conductor ends into the copper sleeve and perform a secure crimp. After crimping, apply heat evenly to the shrink tubing using a heat gun or suitable heat source until the tubing contracts and forms a tight seal around the conductors and sleeve. Allow the connector to cool before handling to ensure a complete shrink and adhesive bond if the tubing includes an adhesive layer.

Usage recommendations

For best results use a correctly sized crimping tool and a controlled heat source (heat gun) to avoid overheating. Verify the electrical continuity and mechanical strength of the joint after application. Choose connectors matching the conductor cross-section and operating environment; replace any connector that shows signs of damage or corrosion.
