3M 7000133656 Vinyl Insulated Butt Connector 22-18 Awg

Product Description

The 3M 7000133656 is a vinyl insulated butt splice connector designed for joining two wires in a single, inline crimp connection. Rated for 22-18 AWG wire, it features chamfered barrel ends that allow fast wire insertion from both ends without fumbling or misalignment. A built-in wire stop provides correct positioning before crimping, reducing the chance of a cold or incomplete crimp. This connector must be crimped at both ends to achieve a secure, electrically sound termination. Electricians, HVAC technicians, and panel wiring professionals use this type of connector on low-voltage control wiring, appliance wiring, and general electrical repairs.

This butt connector is suited for residential and light commercial electrical work where 22-18 AWG conductors are terminated inline. Common applications include low-voltage thermostat wiring, control circuit splices, appliance repair, and automotive wiring. The vinyl insulation sleeve provides a basic level of protection against abrasion and short-circuit contact in dry, indoor environments. Sold in a pack of 10 bags, this connector is a practical addition to a service tech's terminal assortment.

Key Features

• Accepts 22-18 AWG wire range for versatile inline splicing
• Chamfered barrel ends allow fast, easy wire insertion from both sides
• Built-in wire stop ensures correct conductor positioning before crimping
• Must be crimped at both ends for a complete, secure connection
• Vinyl insulation sleeve provides abrasion resistance in dry environments

Compatibility

Designed as an OEM-style butt splice connector compatible with 22-18 AWG stranded or solid conductors used in general electrical, low-voltage control, and appliance wiring applications.

Installation Notes

Installation should be performed by a qualified electrician or licensed trade professional in accordance with applicable NEC requirements. De-energize the circuit completely before making any wire terminations. Use a ratcheting crimp tool rated for vinyl insulated terminals to ensure full, consistent crimps at both barrel ends. Do not attempt to solder over a crimped connection, as this can cause conductor brittleness at the splice point.
