Aci 107667 Crimp Wire Ferrule 12 Awg Partially Insulated

Product Description

The ACI 107667 is a partially insulated crimp wire ferrule designed for use with 12 AWG (4 sq mm) stranded conductors. Ferrules of this type provide a clean, secure termination at the end of a stranded wire, preventing fraying and ensuring consistent contact pressure when the wire is inserted into a terminal block, din rail device, or similar screw-clamp connector. The gray partial insulation collar identifies the 12 AWG gauge range and protects the insulation transition point during and after crimping. Installation requires a ratcheting ferrule crimping tool sized for the appropriate die. The pin measures 18 mm in length with a 3.2 mm pin diameter and an overall length of approximately 25.5 mm.

This ferrule is used in control panel wiring, industrial automation cabinets, HVAC control boards, building automation systems, and other low-voltage or line-voltage wiring applications where stranded conductors must terminate into a compression-style terminal block. Electricians and controls technicians install ferrules during panel builds and field wiring tasks. Sold individually with a minimum order quantity of 100 units, making them well-suited for bulk panel assembly work.

Key Features

• Partially insulated design with gray collar for quick 12 AWG gauge identification
• Crimp connection type ensures a gas-tight, vibration-resistant termination
• 18 mm pin length suits standard terminal block depth requirements
• Compatible with 12 AWG stranded wire (4 sq mm cross-section)
• Prevents conductor fraying at screw-clamp and spring-cage terminal entries

Compatibility

Designed as an OEM-style crimp ferrule for 12 AWG stranded conductors used in terminal block and panel wiring applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC guidelines for terminal wiring. Always de-energize the panel or circuit before terminating or re-terminating conductors. Use a ratcheting ferrule crimping tool with the correct die size for 12 AWG to achieve a proper crimp; do not substitute pliers or non-rated tools. Verify that the receiving terminal block is rated for the ferrule pin diameter before insertion.
