Reliable Inline Wire Joining with Hellermann Tyton Red Butt Splice Connectors

Precision Crimp Connectors for 0.5–1.5 mm² Conductors

The Hellermann Tyton Red Butt Splice In-line Crimp Connectors provide a secure, low-resistance connection for joining two wires end-to-end. Designed for 0.5 to 1.5 mm² conductors, these connectors are ideal for automotive, marine, and general electrical applications where a durable inline splice is required. The double-grip design ensures both the conductor and insulation are firmly held, reducing the risk of wire pull-out and improving long-term reliability.

Manufactured from high-conductivity copper with a tin plating, these butt splices resist corrosion and maintain consistent electrical performance. The red PVC insulation sleeve offers easy identification and provides electrical isolation up to 600 V, with a maximum current rating of 19 A. *Note typical de-rating factors apply based on installation conditions.

Engineered for Consistent Crimp Quality

Each connector features a seamless barrel that promotes uniform crimping, minimising the chance of hot spots or high-resistance joints. The flared entry guides the wire into position, speeding up assembly and reducing installation errors. When used with the recommended HYYT7 crimp tool, these connectors achieve a gas-tight crimp that protects against oxidation and vibration-induced loosening.

Key Features

• Double-grip design secures both conductor and insulation for enhanced strain relief
• Tin-plated copper barrel for excellent conductivity and corrosion resistance
• Flared entry for fast, accurate wire insertion
• Colour-coded red insulation for quick size identification
• Rated for up to 600 V and 19 A (subject to de-rating)
• Compatible with HYYT7 crimp tool for optimal results

Applications Where Reliability Matters

These butt splice connectors are suited to a range of low-voltage wiring tasks, including automotive harness repairs, trailer wiring, marine electronics, and control panel assembly. The compact 25 mm length and 4.0 mm diameter allow installation in tight spaces, while the PVC insulation remains flexible across a wide temperature range, with an operating limit of +75 °C.

By choosing Hellermann Tyton, you benefit from precision manufacturing and consistent quality control, reducing the likelihood of field failures caused by substandard terminations. Whether you are performing a single repair or building a complete wiring loom, these connectors help maintain system integrity.
