3M 7000132258 Insulated Butt Connector 16-14 Awg

Product Description

The 3M 7000132258 is an insulated butt connector designed for splicing two conductors in a single inline crimp joint. Rated for 16-14 AWG wire, it features chamfered barrel ends on both sides that guide wire strands in quickly and reduce insertion effort. A built-in wire stop positions each conductor at the correct depth before crimping, helping technicians achieve consistent, repeatable terminations. This connector is sold individually and is a standard tool for electricians and low-voltage installers working on control wiring, panel work, and field splices.

This butt connector suits residential and light commercial electrical work where inline wire splices are required. It is appropriate for use in HVAC control circuits, appliance wiring, automotive harnesses, and general electrical panel or junction box applications where a secure, insulated crimp termination on 16 AWG or 14 AWG conductors is needed. The insulated sleeve protects the crimped joint from incidental contact in tight enclosures.

Key Features

• Accepts 16-14 AWG wire for a common residential and control-circuit size range
• Chamfered barrel ends on both sides allow fast wire insertion from either direction
• Built-in wire stop ensures correct conductor positioning before crimping
• Insulated construction protects the completed splice from shorts and incidental contact
• Crimp-style termination — no solder required, compatible with standard ratchet crimp tools

Compatibility

Designed as an OEM-style insulated butt splice connector compatible with 16-14 AWG conductors using standard crimp tooling.

Installation Notes

Installation should be performed by a qualified electrician or trained technician following applicable NEC requirements. De-energize the circuit completely before making any splice. Strip conductors to the appropriate length, insert fully until the wire stop is felt, and crimp both ends using a ratcheting crimp tool rated for insulated connectors. Do not apply heat or attempt to solder this connector.
