3M Scotchlok UY2 Butt Splice Connector, 22-26 AWG, Gel-Filled, Transparent, 100 Pack

When joining two solid copper conductors in communication circuits, moisture ingress and unreliable connections are common failure points. The 3M Scotchlok UY2 butt splice connector eliminates these issues with a gel-filled, insulation displacement design that requires no stripping or special tools. Simply insert the wires and press—the connector bites through insulation, creates a gas-tight connection, and the hydrophobic gel seals out moisture for long-term reliability.

Who is it for

Telecom technicians, network installers, and maintenance crews working on telephone, data, or low-voltage control wiring will appreciate the speed and dependability of these connectors. Whether you're splicing in tight spaces, repairing outdoor lines, or doing high-volume installations, the UY2 is a proven solution.

Tips

For best results, ensure wires are fully inserted until they stop against the connector's end wall. Use parallel-jaw pliers to apply even pressure on the cap until it is flush with the body. The transparent housing lets you confirm proper seating before crimping. Store connectors in a dry place to preserve the gel sealant.
