3M 7000133655 Vinyl Insulated Butt Connector 16-14 Awg

Product Description

The 3M 7000133655 is a vinyl insulated butt splice connector rated for 16-14 AWG wire. It creates a reliable in-line wire splice in residential, commercial, and light industrial electrical applications. Chamfered barrel ends allow fast wire insertion from both ends, and a built-in wire stop ensures correct wire positioning before crimping. Both ends require crimping to complete the connection. Electricians and field technicians use this connector when joining two conductors end-to-end in branch circuit wiring, control wiring, and low-voltage applications.

This connector is suited for use in electrical panels, junction boxes, appliance wiring, HVAC control circuits, and general wire repair work. The vinyl insulation sleeve provides a protective outer layer over the crimped barrel. Sold in a pack of 10 bags, making it a practical stock item for service vans and electrical supply kits. The 16-14 AWG wire range covers the most common gauge sizes used in residential and light commercial wiring runs.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize the circuit completely before making any wire connections. Use a calibrated ratcheting crimp tool sized for the connector barrel to achieve a proper mechanical and electrical crimp at both ends. Do not use pliers or uncalibrated tools as a substitute for a proper crimping tool, as an inadequate crimp can result in a high-resistance connection or pull-out failure.
