Sleeve (tulejka) Aptel 7618-20-8 — metal connector sleeve for cable/wire joints

Aptel Tulejka 7618-20-8 is a tubular metal connector sleeve designed to create mechanically secure and electrically conductive splices between cable and wire ends. Manufactured for use in electrical installations and repair work, this metal sleeve is intended for crimping applications where a stable joint and reliable current transfer are required. The sleeve is suitable for joining solid and stranded conductors in low-voltage systems and for routine maintenance tasks in residential, commercial, and light industrial environments.

Advantages

The metal construction ensures consistent conductivity and mechanical strength across the connection, while the tubular shape provides uniform compression during crimping. The sleeve supports reliable electrical contact and reduces the risk of loose or intermittent joints when properly installed. Its compact form factor allows use in confined spaces and standard crimping tools can be used for installation.

Suitable for

• Crimped splices of copper conductors in low-voltage electrical circuits
• Cable terminations during installation and repair work
• Joining solid and stranded wires in distribution and control wiring
• Maintenance tasks where a compact, conductive mechanical splice is needed

Key specifications

• Material: tubular metal construction for electrical conductivity
• Design: straight tubular connector for crimping
• Intended use: mechanical and conductive splice for cable and wire joints
• Application environment: low-voltage installations, maintenance, and repair
• Compatibility: suitable for solid and stranded copper conductors of appropriate gauge

How to use

Strip insulation from each conductor to the recommended length, insert both wire ends into the sleeve so they meet centrally, then position a suitable crimping tool over the sleeve and apply a compressive crimp according to the tool and sleeve specifications. After crimping, inspect the connection visually and, if required, perform a pull test to confirm mechanical stability. Where necessary, apply insulation tape or heat-shrink tubing over the completed splice to restore insulation and provide environmental protection.

Usage recommendations

Use the sleeve only with conductors and crimping tools matched to the sleeve dimensions and material. Select the correct conductor cross-section and follow applicable electrical installation regulations. Avoid using the sleeve in high-voltage or highly corrosive environments unless additional protective measures are taken.
