3M 7100021008 Vinyl Insulated Butt Connector

Product Description

The 3M 7100021008 is a vinyl insulated butt connector sold in bottles of 100, designed for splicing two conductors end-to-end in a reliable, insulated termination. The vinyl sleeve provides electrical insulation and basic strain relief at the crimp point. These connectors are a standard consumable used by electricians, HVAC technicians, and other trade professionals wherever wire splicing is required on low-voltage or line-voltage circuits. The minimum order quantity is 100 units per bottle, making them well suited for high-volume service work, panel builds, and equipment wiring.

Vinyl insulated butt connectors of this type see use across residential and light commercial applications, including HVAC control wiring, appliance repair, panel and junction box work, and general electrical service. They are crimped onto stripped conductors using a standard hand or ratchet crimp tool. The bottle packaging keeps connectors organized and accessible on the job site or in a service vehicle parts inventory.

Key Features

• Vinyl insulation provides electrical isolation at the splice point
• Butt-crimp design joins two conductors end-to-end without soldering
• Sold in bottles of 100 for high-volume service and stocking
• Compatible with standard hand crimp and ratchet crimp tooling
• Compact, organized bottle packaging for bench or van storage

Compatibility

Designed as an OEM-style crimp termination solution for use in residential and light commercial electrical and low-voltage wiring applications where vinyl insulated butt splices are specified.

Installation Notes

Installation is performed by licensed electricians or qualified trade technicians in accordance with NEC requirements for the circuit type and voltage involved. De-energize and lock out the circuit before stripping conductors and inserting them into the connector barrel. Use a calibrated crimp tool appropriate for the wire gauge and connector series to ensure a gas-tight crimp. Do not apply heat or attempt to solder vinyl insulated connectors, as the vinyl sleeve is not rated for heat-shrink application.
