Moisture-Resistant Insulation-Piercing Butt Splices

Connect wire without stripping—these splices pierce the insulation for quick installation. The pigtail connections have a gel seal to protect the connection from humidity, water, and dirt.

Pliers (sold separately) are recommended to install wire.

Push-On Wire Splicing Connectors

Push stripped wires into connectors for a reliable connection that's faster to install than twisting or crimping. All have individual ports for each wire.

Connectors with a 600V AC/DC maximum voltage have a clear housing, so you can visually confirm your connection.

DIN rail adapters (sold separately) allow you to mount the connector to a 35 mm DIN rail.

Insulation-Piercing Wire Taps

Tap/Main

2-Wire Pigtail

Inline

Double Run

Connect a tap wire to a main wire without stripping—these wire taps penetrate insulation. To install, squeeze the tap with standard pliers; a built-in U-shaped metal contact penetrates the insulation and grips the wire.
