Crimp connector sleeve Erko KLA 2.5 x 15 mm, copper, pack of 100

Erko KLA 2.5 x 15 mm is a copper crimp connector sleeve supplied in a pack of 100. Designed for joining and extending copper conductors, this 2.5 x 15 mm sleeve provides reliable electrical contact and mechanical stability when crimped. The sleeve is intended for use in electrical installations, automotive wiring repairs and other situations where a secure, low-resistance connection between copper conductors is required.

Advantages

The copper construction ensures good electrical conductivity and corrosion resistance for typical indoor and protected-environment applications. Supplied in a pack of 100, the sleeves offer convenient quantity for recurring installation tasks or small service jobs. When properly crimped with the correct tool, the sleeve creates a compact joint with consistent mechanical strength and low contact resistance, reducing the risk of loose connections.

Suitable for

• Joining and extending copper conductors of compatible cross-section
• Electrical installation work in residential and commercial settings
• Automotive wiring repairs and maintenance
• Appliance servicing and control panel connections

When it may not be suitable

This crimp connector sleeve is designed specifically for copper conductors; it is not intended for use with aluminium wiring without appropriate transition fittings. It may not be suitable for exposed outdoor installations where direct environmental exposure, vibration or corrosive conditions require additional protective measures such as sealing, insulation or terminals rated for harsh environments.

Key specifications

• Material: copper
• Nominal cross-section compatibility: 2.5 mm²
• Length: 15 mm
• Quantity per pack: 100 pieces
• Connection method: crimp

How to use

Strip the insulation from the ends of the copper conductors to the appropriate length for insertion into the sleeve. Insert the conductors fully into the sleeve so that the conductor strands are inside the copper tube. Use a suitable crimping tool sized for 2.5 mm² sleeves and apply a single solid crimp at the correct position to compress the sleeve onto the conductors. After crimping, inspect the joint for secure mechanical hold and, if required, apply insulating tubing or heat-shrink over the sleeve to protect against moisture and mechanical abrasion.

What to consider before purchase

• Confirm conductor type is copper and cross-section matches 2.5 mm²
• Ensure you have an appropriate crimping tool for 2.5 mm² sleeves
• Evaluate environmental conditions and whether additional sealing or insulation is needed
• Check quantity per pack (100) matches your project requirements

Usage recommendations

For reliable results, use a calibrated crimping tool designed for insulated or uninsulated copper sleeves of this size, follow the tool manufacturer's crimping instructions, and protect the crimped joint with heat-shrink tubing or appropriate insulation when used in environments subject to moisture or mechanical stress.
