These twist-on wire caps ensure a secure, reliable connection for all standard low-voltage applications. Engineered with a durable zinc-plated core and a UL94V-2 flame-retardant thermoplastic shell, they feature an internal spring design that grips wires tightly for a superior, long-lasting hold. They are gel-filled and designed to protect wire splices in damp, wet, or outdoor environments. The internal silicone gel prevents moisture, dirt, and corrosion from reaching the copper, making them ideal for landscape lighting, sprinkler systems, and underground or exposed wiring.
