3M 7000133319 Vinyl Insulated Butt Connector 100pk

Product Description

The 3M 7000133319 is a seamless vinyl-insulated butt connector sold in bottles of 100 pieces. Butt connectors join two wire ends in a straight inline splice, providing a secure mechanical and electrical connection without the need for soldering. The seamless vinyl insulation sleeve covers the metal barrel to help protect the splice from contact with adjacent conductors or enclosure surfaces. This connector is a staple in residential and commercial electrical work, as well as HVAC low-voltage wiring, panel work, and equipment service where quick, reliable wire splices are required. Licensed electricians and HVAC technicians are the primary installers.

This butt connector is appropriate for inline wire splicing in control circuits, field wiring terminations, and general electrical applications. The 100-piece bottle format makes it practical for stocking a service van or shop inventory. The part number MV14BCX is referenced in the supplier product description and is useful for cross-referencing this connector across distributor catalogs.

Installation Notes

Installation should be performed by a qualified electrician or HVAC technician in accordance with NEC requirements for the application. Always de-energize the circuit at the breaker or disconnect before making any splice connections. Use an appropriate ratcheting or calibrated crimp tool matched to the connector size to ensure a secure mechanical and electrical crimp. Avoid pulling on the wire after crimping to verify the connection is seated before closing the enclosure or junction box.
