Connector sleeve Red Marka ABG M40 — cable jointing mufа 40 mm

Red Marka ABG M40 connector sleeve is a compact mechanical jointing mufa designed for joining and extending cables and conductors in electrical installations. With an outer dimension of 40 mm, this sleeve provides a stable, space-saving connection point where insulation continuity and mechanical integrity are required. The product is intended for straightforward cable splicing in domestic, commercial, and light industrial wiring where a small, reliable sleeve is preferable.

Advantages

The connector sleeve offers a straightforward mechanical connection that does not require complex tools or heat-shrink processes, enabling fast installation. Its compact 40 mm form factor conserves space in junction boxes and behind panels. The design ensures a firm grip on conductors and helps maintain electrical continuity while minimizing bulk at the joint. The sleeve is suitable for use with common copper conductors and typical insulation types encountered in building wiring.

Suitable for

• Joining and extending single-core and multi-core electrical cables in residential wiring
• Creating compact splices in junction boxes and distribution cabinets
• Repairing damaged cable runs where a small mechanical sleeve is sufficient
• Temporary or permanent mechanical cable connections in commercial fit-outs

Key specifications

• Outer dimension: approximately 40 mm (model M40)
• Type: mechanical connector sleeve for cable jointing
• Suitable conductor materials: common copper conductors
• Application: splicing and extending electrical cables in tight spaces
• Installation environment: indoor electrical installations, junction boxes, panels

How to use

Prepare cable ends by stripping insulation to the appropriate length for the sleeve and ensure conductors are clean and free of corrosion. Insert conductors into the sleeve so that they overlap or meet according to standard splicing practice, then secure the mechanical connection according to the sleeve's assembly method (for example, by crimping, screwing, or compressing as applicable). After joining, verify mechanical tightness and electrical continuity with suitable test equipment, and restore insulation or place the joint within a junction box or protective enclosure.

Usage recommendations

Use the connector sleeve only with compatible conductor sizes and types; avoid exposing the joint to prolonged moisture or corrosive conditions without additional sealing. Confirm the selected sleeve meets local electrical codes and current-carrying requirements for the intended circuit. When in doubt, consult a qualified electrician to ensure safe installation and compliance.
