3M 7000133313 Non-insulated Seamless Butt Connector

Product Description

The 3M 7000133313 is a seamless, non-insulated butt connector sold in bottles of 100. It is used to join two wire ends in a single in-line crimp connection without the added bulk of an insulating sleeve. The seamless barrel construction provides a clean, uniform crimp that reduces the risk of wire pullout. This connector is suited for electrical wiring applications where a separate insulating sleeve, heat shrink, or tape will be applied after crimping. Electricians and wire harness technicians are the primary installers.

This butt connector is designed for applications where the installer controls the insulation method independently from the connector. Typical use cases include automotive wiring, panel wiring, and low-voltage electrical assemblies where consistent, high-volume terminations are required. The 100-count bottle format makes it practical for bench work and field service kits where repeated terminations are performed in a single session.

Key Features

• Seamless barrel construction for uniform crimp and secure wire retention
• Non-insulated design allows installer-applied insulation method of choice
• Sold in 100-count bottles for high-volume wiring work
• Compact form factor minimizes added bulk at the termination point

Compatibility

Designed as an OEM-style non-insulated butt connector for general electrical wiring and termination applications requiring a bare crimp splice.

Installation Notes

Installation is performed using a standard ratcheting or plier-style crimp tool rated for non-insulated terminals. Confirm wire gauge matches the connector's rated range before crimping. After crimping, apply an appropriate insulating sleeve, heat shrink tubing, or electrical tape per applicable NEC requirements. Inspect each crimp for a complete, flush barrel before energizing the circuit.
