3M Scotchlok Butt Connector UR

UR Butt Connectors are real time savers. They enable the user to tap into another wire or other two wires without interrupting service. A U-shaped element inside each connector displaces insulation material and makes contact with the copper conductor. UR Butt Connectors also include factory-installed sealant to protect against corrosion and seal out moisture. UR Butt Connectors are fast to install, easy to work with and available in a wide range of common wire gauges. UR Butt Connectors allow direct tapping into existing solid copper conductors without interrupting service. The pre-crimp feature helps hold the wires in place until the connector is crimped and the splice is complete.

UR Butt Connectors are compatible with copper wires of 0.4-0.9mm (19-26 AWG). The gel filled IDC contact area protects connections from moisture penetration.

All materials used in the connectors are non-toxic and dermatologically safe.
