Hellermann Tyton Blue In-Line Butt Splice Crimp Connectors for Reliable Wire Joining

Professional-Grade Splice Connectors for 1.5–2.5 mm² Cables

The Hellermann Tyton Blue Butt Splice In-line Crimp Connectors provide a secure, low-resistance connection for joining two wires end-to-end. Engineered for 1.5–2.5 mm² conductors, these connectors are ideal for automotive, marine, and industrial wiring applications where dependable performance is critical.

Unlike generic splice connectors, Hellermann Tyton’s design features a seamless copper barrel that ensures uniform crimping and maximum conductivity. The colour-coded blue PVC insulation simplifies identification and offers excellent electrical isolation, reducing the risk of short circuits or corrosion over time.

Why Choose Hellermann Tyton Butt Splice Connectors?

In demanding environments, poor-quality connectors can lead to voltage drop, overheating, or intermittent faults. These butt splice crimp connectors address those risks with precision manufacturing and robust materials:

• Seamless copper barrel – promotes even compression and reliable current flow
• Flared entry – guides wires smoothly into the barrel for faster, frustration-free insertion
• Colour-coded PVC insulation – blue for 1.5–2.5 mm², meeting industry standards for quick gauge recognition
• Rated to 600 V and 27 A – suitable for a wide range of low-voltage DC and AC circuits
• Operating temperature up to +75 °C – handles under-bonnet and enclosed equipment heat

*Note typical de-rating factors apply; maximum current rating assumes proper crimping and installation conditions.

Applications Across Automotive, Marine, and Industrial Systems

These inline crimp connectors are a versatile solution for anyone working with electrical wiring. Common uses include:

• Repairing or extending 12 V automotive wiring in cars, 4WDs, and trailers
• Marine electronics and navigation lighting, where vibration and moisture resistance are essential
• Control panels, machinery, and appliance wiring in industrial settings
• DIY electrical projects requiring a neat, permanent inline splice

With a maximum voltage rating of 600 V, these connectors are also suitable for 24 V and 48 V systems, offering flexibility beyond typical 12 V applications.

Built for Consistent, Long-Term Performance

Hellermann Tyton’s manufacturing quality reduces common failure points. The copper barrel resists cracking under vibration, while the PVC insulation sleeve provides strain relief and protects against abrasion. When crimped with a matching tool, the connection achieves a gas-tight bond that minimises oxidation and maintains low contact resistance over the service life of the installation.

For professionals and enthusiasts who value reliability, these butt splice connectors deliver peace of mind—whether you’re rewiring a trailer, tidying up an engine bay, or building a custom harness.
