Klauke 167H Insulated Ferrule 0.25 mm², White, 6 mm Metal Tube, Pack of 500

Precision-crimped connections start with a ferrule that fits the conductor exactly. The Klauke 167H insulated ferrule is engineered for 0.25 mm² fine-stranded wires, with a 6 mm tin-plated copper tube that protects against fraying and a funnel-shaped polypropylene collar for fast, snag-free insertion. Unlike generic sleeves, its DIN 46228 Part 4 compliance and halogen-free insulation deliver consistent, repeatable terminations in control cabinets, building automation, and industrial wiring.

Highlights

• Optimised for 0.25 mm² fine-stranded conductors
• Tin-plated electrolytic copper tube for low contact resistance and corrosion resistance
• Funnel-shaped entry guides the wire into the barrel without strand folding
• White polypropylene insulation colour-codes the size for quick identification
• Halogen-free and RoHS compliant for safer installations
• Supplied in a bulk pack of 500 pieces for high-volume work

In daily use

The 167H ferrule is the workhorse of terminal blocks, PLC connections, and sensor wiring. Its 12.5 mm total length and 2.5 mm insulation diameter fit standard crimping tools with 0.25 mm² dies. The polypropylene collar withstands temperatures from -40 °C to +105 °C, so the ferrule remains stable in harsh environments, while the UL 94 V-2 flammability rating adds an extra margin of safety. Whether you are building a new panel or repairing a machine, the 167H keeps every strand captured and every connection secure.
