Klauke 27R Tube Crimp Connector for 70 mm² Copper Conductors, Tinned, 60 mm Length

Secure, low-resistance connections for 70 mm² copper conductors demand a connector that maintains integrity under mechanical stress and thermal cycling. The Klauke 27R tube crimp connector answers that need with a robust, tinned electrolytic copper design, engineered for reliable hexagonal crimping and long-term performance in low-voltage applications.

Who is it for

Electricians, panel builders, and maintenance technicians working with power distribution, grounding systems, or industrial machinery will find the 27R indispensable. It suits professionals who require a dependable, corrosion-resistant connection for solid or stranded copper conductors without insulation.

Main features

• High-purity electrolytic copper (E-Cu) with galvanic tin plating for excellent conductivity and corrosion resistance.
• Designed for 70 mm² copper conductors, with a built-in conductor stop for accurate insertion.
• Hexagonal crimping profile ensures a uniform, gas-tight connection when used with recommended Klauke tools.
• Compact 60 mm length with 11.5 mm inner diameter and 15 mm outer diameter, suitable for tight spaces.
• Operating temperature range from -40°C to +125°C, RoHS compliant.

Tips

For optimal results, use Klauke crimping tools recommended for hexagonal profiles. Ensure the conductor is fully inserted until it meets the stop, and verify the crimp with a gauge if available. The tinned surface allows soldering if required, but crimping alone provides a reliable connection.
