Silicone Filled Wire Nuts by Highpoint
Highpoint wire-filled electrical nuts (also called Highpoint silicone-filled waterproof wire nuts) are twist-on electrical connectors specifically designed for low-voltage outdoor lighting applications, such as deck lights, post cap lights, stair lights, landscape lighting, and other wet-location wiring.
Key features
- Silicone-filled – Each connector is pre-filled with silicone gel that completely surrounds the wire splice, sealing out moisture and preventing corrosion.
- Waterproof – Suitable for wet locations, making them ideal for deck and landscape lighting connections exposed to rain and snow.
- Twist-on installation – Strip the wires, insert them into the connector, and twist until tight. The internal spring secures the conductors while the silicone seals the connection.
- Corrosion protection – The silicone gel helps prevent oxidation, which is one of the most common causes of low-voltage lighting failures outdoors.
Available sizes
- 18 AWG – For 18-gauge low-voltage lighting wire.
Common applications
They're commonly used to connect:
- LED deck lights
- Stair lights
- Rail lights
- Post cap lights
- Landscape lighting fixtures
- Transformer leads
