3M 7000149334 Vinyl Insulated Butt Connector 50/bottle

Product Description

The 3M 7000149334 is a seamless vinyl-insulated butt connector sold in bottles of 50. Butt connectors are used to join two wire ends in a straight inline splice, creating a secure, insulated termination. The seamless vinyl insulation eliminates exposed seams that can snag or crack during installation, helping maintain a clean, protected splice. This connector is a standard consumable stocked by electrical contractors, HVAC technicians, and other trade professionals who perform frequent wire termination work. The minimum order quantity is 50 connectors per bottle, making it practical for both job-site replenishment and shop inventory.

This connector is suited for general wire splicing applications across residential and light commercial electrical, HVAC control wiring, and panel work. Technicians reach for vinyl-insulated butt connectors when terminating branch circuits, control leads, or sensor wiring where a compact, insulated inline splice is required. The 50-count bottle format is common on service trucks and in shop bins.

Installation Notes

Butt connectors of this type are installed by licensed electricians and HVAC technicians in accordance with NEC requirements for spliced conductors. Always de-energize the circuit and verify zero voltage with a meter before making any splice. Use a calibrated crimping tool rated for insulated terminals to achieve a proper mechanical and electrical connection. Do not attempt to solder over a crimped vinyl-insulated connector, as heat can damage the insulation.
