Low Voltage Wire Connectors Landscape Lighting Connector 12-18 Gauge UL Listed Cable Splice Connector Waterproof for Landscape Lighting/Pathway Light/Spotlight, Pack of 8

What It Is

These are waterproof, UL-listed low voltage wire connectors designed for splicing 12-18 gauge landscape lighting cable. They’re used to connect pathway lights, spotlights, and other low voltage outdoor fixtures to the main power run.

Fitment & Compatibility

• Wire gauge: Works with 12, 14, 16, and 18 gauge stranded or solid copper wire only. Not for aluminum or steel wire.
• Voltage: Rated for low voltage (12V-24V) landscape lighting systems only. Do not use with line voltage (120V) or extension cords.
• Cable type: Best with direct burial or outdoor-rated landscape lighting cable (typically two-conductor).
• Connector type: These are gel-filled, push-in splice connectors, not twist-on or crimp style. They work with both cut ends and mid-run taps.

Before buying: Measure your existing cable gauge. If you have mixed gauges in the same run, confirm the connector can handle both (these can, but check the package for max/min range). Not compatible with thick jacketed Romex or UF-B cable.

Key Things to Know

• Waterproofing: Gel inside creates a moisture-proof seal without heat shrink or tape. Works in wet locations and underground splices.
• Installation: No tools required—strip 1/2" of insulation, push wire into the slot until it clicks, and close the lid. Takes about 30 seconds per splice.
• Reusability: Not reusable. Once closed, you can’t remove the wire without cutting the connector off.
• Common gotcha: If your wire is too stiff (e.g., 12 gauge solid), you may need to gently twist it while pushing in. For very short branch runs, leave enough slack to reach the connector easily.

Should You Buy It

Buy these if you’re installing or repairing low voltage landscape lighting and want a fast, reliable, waterproof splice without soldering or heat shrink. They’re ideal for DIYers who need a simple, no-tool solution for 12-18 gauge outdoor cable. Skip them if you’re working with line voltage, aluminum wire, or need a reusable connector.
