3M 7000031368 Copper Barrel Connector 35 Kv 6 Awg

Product Description

The 3M 7000031368 is a copper standard barrel connector rated for use up to 35 kV on 6 AWG copper conductors. Sold individually, this connector is manufactured from one-piece, seamless, high-conductivity copper with a blue color code indicating 6 AWG sizing. The body measures 1.75 inches in length with an inner diameter of 0.20 inches. It is designed for electricians and utility technicians performing splices and terminations on copper conductors in medium-voltage electrical installations. The seamless construction eliminates internal seams that could create weak points under load or environmental stress.

This barrel connector is suited for medium-voltage copper conductor splicing applications up to 35 kV. It is typically used in residential, commercial, and utility electrical work where a reliable, low-resistance copper-to-copper connection is required. The blue color coding allows technicians to quickly identify the correct connector for 6 AWG conductor work during installation.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements and local electrical codes. De-energize and lock out the circuit before making any connections. Use only on copper conductors as specified — do not use on aluminum or aluminum-clad conductors. Ensure proper crimping tooling is used per the manufacturer's requirements to achieve a secure, low-resistance connection.
