Insulated ferrule Elpromet E2508, insulated bootlace ferrules 2.5 mm², 8 mm length, blue, pack of 100

Insulated bootlace ferrules Elpromet E2508 are designed for terminating stranded conductors with a cross-section of 2.5 mm². Each ferrule combines a blue polyamide insulating collar with an 8 mm metal crimp tube to provide a secure mechanical connection and improved electrical contact in screw or clamp terminals. Supplied in a pack of 100, these ferrules are intended for electrical panels, control cabinets and general field wiring where uniform crimps and resistance to vibration are required.

Advantages

The insulated barrel reduces the risk of stray strands and ensures consistent compression during crimping, improving contact reliability. The polyamide collar provides electrical insulation and strain relief at the conductor entry, while the tin-plated metal tube resists corrosion and delivers stable conductivity. Packaging in a 100-piece pack streamlines inventory and reduces handling time on repeated installation tasks.

Suitable for

• Termination of 2.5 mm² stranded copper conductors in screw terminals
• Wiring inside distribution boards and control cabinets
• Field installations and maintenance where vibration resistance is needed
• Applications requiring uniform crimp quality for multi-core cables

Key specifications

• Conductor cross-section: 2.5 mm²
• Insulation material: polyamide (blue)
• Metal tube length: 8 mm
• Recommended use: crimp termination for stranded conductors
• Pack quantity: 100 pieces

How to use

Strip the conductor to the appropriate length so the bare strands fully enter the metal tube without exposing insulation beyond the collar. Insert the conductor into the ferrule until the wire reaches the base of the metal tube. Use a properly sized manual or hydraulic crimping tool with a die suitable for 2.5 mm² bootlace ferrules and apply a single, firm crimp to compress the tube uniformly. After crimping, inspect the ferrule to confirm that the strands are secured and that the polyamide collar fits snugly against the cable insulation.

Usage recommendations

Choose a crimping tool designed for insulated bootlace ferrules and matched to the 2.5 mm² size to achieve consistent joint quality. Avoid reusing ferrules after removal; replaced ferrules should be new to maintain reliable electrical and mechanical connections. Store the pack in a dry environment away from direct sunlight to preserve the polyamide insulation.
