Ring ferrule Erko KCS M12 x 185 mm copper tubular connector, pack 10

Erko KCS M12 x 185 mm copper ring ferrule supplied as a pack of 10 is designed for forming secure ring-style terminations on M12 studs and bolts. The tubular copper construction provides consistent electrical contact and mechanical protection for conductor ends, simplifying assembly and ensuring stable connections in electrical and industrial installations where reliable conductor fixation is required.

Advantages

The copper tubular design offers low electrical resistance and good corrosion resistance for durable contact. The elongated 185 mm length allows insertion of longer conductors and provides additional insulation overlap when used with heat-shrink or insulating sleeves. Supplied in a pack of 10, the ferrules are convenient for batch installations and maintenance tasks, reducing handling time and ensuring consistent ring termination geometry for repeated assemblies.

Suitable for

• Terminating stranded or tinned conductors on M12 studs and bolts
• Power and control wiring in industrial panels and switchgear
• Field service repairs and routine electrical maintenance
• Applications requiring secure mechanical clamping and reliable electrical contact

Key specifications

• Material: copper tubular construction
• Ring size: compatible with M12 studs/bolts
• Length: 185 mm
• Pack quantity: 10 pieces

How to use

Prepare the conductor by stripping insulation to the appropriate length, insert the conductor fully into the copper tube, and crimp the ferrule using a suitable crimping tool matched to the conductor cross-section. Place the ring over the M12 stud or bolt and secure with the appropriate nut and washer to achieve firm mechanical and electrical contact. If additional environmental protection is needed, apply an insulating sleeve or heat-shrink tubing over the junction after installation.

Usage recommendations

Choose a crimping tool and die suitable for the conductor cross-section to ensure a reliable crimp. Verify that conductor strands are fully inserted before crimping and inspect connections for tightness and correct positioning on the stud. For installations exposed to moisture or corrosive environments, consider supplementary insulating or sealing measures.
