Our 24-piece set of waterproof wire electrical connectors is designed with versatility in mind, offering 12 blue connectors and 12 black connectors. These connectors are compatible with a wide range of wire gauges, including 12AWG to 22AWG, ensuring they meet the diverse needs of various electrical projects. Constructed from high-quality PVC material, these waterproof wire nuts are not only sturdy and but also flexible, allowing them to withstand temperatures from -40℉ to 400℉. Their ability to handle up to 600V makes them a safe choice for reducing fire risk and protecting your wiring investments. Featuring an IP65 waterproof design, these connectors are pre-filled with an appropriate amount of silicone sealant, providing a weatherproof, moisture-proof solution. This makes them ideal for use in wet environments where they may be exposed to condensation, water, steam, or dust. Installation of these waterproof wire nuts is straightforward and does not require pre-twisting. Simply insert the wire ends into the caps and twist to seal. The silicone sealant will overflow, creating a watertight seal that prevents leakage, even when exposed to water. With their wide range of applications, these connectors are perfect for outdoor or indoor electrical wire splices. They are widely used in outdoor landscape lighting, construction, automotive applications, irrigation systems, and other external wiring setups, making them a valuable addition to any electrical toolkit.
