Frequently Asked Questions

What is a 3M butt splice connector used for?

A 3M butt splice connector joins two wires end-to-end in electrical systems. It is used across industrial departments like machining, material handling, and instrumentation for permanent, reliable connections in control panels, machinery, and power distribution.

What are the specifications of the 3M M14BCK butt splice connector?

The 3M M14BCK is a non-insulated butt splice connector for wire sizes 16 AWG to 14 AWG, rated 600 V. It comes in a pack quantity of 1,000. The bare design allows for custom insulation or use in tight spaces where insulation is not required.

Where to buy 3M butt splice connectors worldwide?

3G Electric supplies 3M butt splice connectors worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine 3M parts like the M14BCK and support procurement across 14 departments.

How to install a non-insulated butt splice connector?

Strip the wire ends to the recommended length, insert each into the connector barrel, and crimp using a tool matched to the wire gauge (16–14 AWG). For the 3M M14BCK, ensure a secure mechanical crimp. If insulation is needed, apply heat shrink or tape after crimping.
