3M 7000132243 Insulated Butt Connector 22-18 Awg

Product Description

The 3M 7000132243 is an insulated butt connector designed for splicing two wires in a single inline termination. It accepts wire gauges from 22 to 18 AWG and requires a crimping tool at both barrel ends to complete the connection. Chamfered barrel ends allow fast, straightforward wire insertion from either side, while a built-in wire stop ensures correct wire positioning before crimping. This connector is suited for low-voltage wiring applications in HVAC controls, electrical panels, and equipment harness repairs where a clean, secure splice is needed.

This butt connector is used in residential and light commercial electrical and HVAC service work. It is appropriate wherever a quick, reliable inline wire splice is required on 22 to 18 AWG conductors. The insulated construction helps protect the termination point from contact with adjacent components. Electricians, HVAC technicians, and equipment service professionals commonly use this connector during control wiring, sensor lead repairs, and accessory wiring tasks.

Key Features

• Wire range: 22 to 18 AWG
• Chamfered barrel ends allow wire insertion from both sides without additional prep
• Built-in wire stop provides consistent wire positioning before crimping
• Insulated construction protects the splice from incidental contact
• Requires crimping at both ends for a secure mechanical and electrical connection
• Sold in a case quantity of 1000 units

Compatibility

Designed as a standard insulated inline butt connector for use with 22 to 18 AWG copper conductors in low-voltage and general wiring applications.

Installation Notes

Installation requires a ratcheting or standard crimping tool rated for insulated connectors in the 22 to 18 AWG range. De-energize all circuits before making or breaking wire connections. Strip wire ends to the appropriate length, insert each conductor fully until it seats against the built-in wire stop, then crimp both ends of the barrel. Follow applicable NEC requirements for wire splicing and termination in the system being serviced.
