Erko tubular crimp ferrule TE tin-plated 2.5 mm² 100 pcs

Erko tubular crimp ferrule TE tin-plated 2.5 mm² 100 pcs are metal end sleeves designed for terminating stranded conductors in electrical installations. The ferrules are tin-plated to improve corrosion resistance and solderability, with an inner barrel sized for 2.5 mm² conductors. Supplied as a pack of 100 pieces, these tubular ferrules are intended to provide consistent strand consolidation for crimp connections used in screw terminals, distribution blocks and relays.

Advantages

These tin-plated tubular crimp ferrules reduce conductor fraying and ensure a neat, compact termination that fits reliably into screw-type connectors. Tin plating enhances resistance to oxidation and improves the contact surface for long-term electrical continuity. The consistent barrel dimensions support repeatable crimps and simplify assembly in production or maintenance tasks.

Suitable for

• Terminating stranded copper conductors with 2.5 mm² cross-section
• Use in screw terminals, distribution blocks and relay connections
• Electrical installations in residential, commercial or light industrial environments
• Maintenance, repair and assembly work where consistent crimp quality is required

When it may not be suitable

These ferrules are sized specifically for 2.5 mm² stranded conductors and are not suitable for solid conductors or wire sizes significantly larger or smaller than the rated cross-section. They are intended for standard crimping tools and may not perform correctly if used with inappropriate crimping pliers or non-compatible tooling.

Key specifications

• Material: tin-plated metal
• Intended conductor cross-section: 2.5 mm²
• Type: tubular crimp ferrule (end sleeve)
• Pack quantity: 100 pieces

How to use

Strip the insulation from the stranded conductor to the recommended length, insert the bare strands fully into the tubular ferrule barrel, and crimp the ferrule with a suitable crimping tool designed for insulated or non-insulated ferrules of this size. After crimping, inspect the connection to ensure the strands are fully captured and the ferrule is deformed uniformly. Fit the terminated conductor into the terminal and tighten the screw to the terminal manufacturer's recommended torque.

What to consider before purchase

• Confirm the conductor cross-section is 2.5 mm² and that the ferrule barrel length and diameter suit your terminal type
• Verify compatibility with your crimping tool and the recommended die for 2.5 mm² ferrules
• Consider whether tin-plating is required for your environment for improved corrosion resistance

Usage recommendations

Use a calibrated crimping tool appropriate for 2.5 mm² ferrules, check crimps visually or with a pull test when required, and follow terminal torque specifications to ensure secure, low-resistance connections.
