Tap Connector

Tap Connectors: Moisture-Resistant Wire Splice Connectors for Secure, Fast Connections

Tap connectors provide a quick, reliable, and efficient method for splicing new wires into existing ones. Designed for convenience, these wire splice connectors eliminate the need for wire stripping, cutting, or soldering, making them a go-to solution for fast electrical connections. One of their key features is the moisture-resistant grease inside the connector, which forms a protective corrosion barrier when closed. This ensures long-lasting, secure connections, even in challenging environments. Tap connectors are commonly used in trailer lighting, automotive wiring, and other applications where quick, moisture-resistant splices are essential.

Built to withstand rigorous conditions, tap connectors are rated for up to 600V and can endure temperatures as high as 90°C (194°F). They are UL Listed and RoHS Compliant, ensuring high safety and quality standards. The internal mineral oil-based dielectric grease prevents moisture, dust, and other harmful substances from penetrating the connection, thereby reducing the risk of corrosion or electrical failure. These connectors support different wire gauges with specific amperage limits: 18-gauge wires support up to 7 amps, 16-gauge wires support 10 amps, and 14-gauge wires support 15 amps.

Tap connectors are an essential component for trailer lighting, automotive repairs, and electrical system modifications. Their ease of use, moisture resistance, and compatibility with a range of wire gauges make them a trusted choice for electricians, technicians, and DIY enthusiasts alike. Offering protection, durability, and quick installation, tap connectors deliver a clean, efficient solution for secure electrical splices that stand the test of time.

Moisture Resistant Connector

Tap Connectors: Moisture-Resistant Wire Splice Connectors for Fast, Reliable Electrical Connections

Tap connectors offer a quick and efficient way to splice a new wire into an existing wire without the need for cutting, stripping, or soldering. These wire splice connectors are designed for simplicity, making them a preferred solution for fast electrical connections. Each connector is pre-filled with a moisture-resistant, mineral oil-based dielectric grease that forms a corrosion-resistant barrier when the connector is closed. This protective layer safeguards the connection from moisture, dirt, and other destructive substances, making tap connectors ideal for trailer lighting, automotive wiring, and other electrical applications requiring durable, long-lasting splices.

Built for performance and reliability, these tap connectors are rated for 600V and can withstand temperatures up to 100°C (212°F). They are compatible with 18, 16, and 14-gauge wires, with specific amperage limits for each size: 18-gauge wires support up to 7 amps, 16-gauge wires support 10 amps, and 14-gauge wires support 15 amps. This versatility makes tap connectors suitable for a variety of electrical setups where efficient, secure splicing is essential. While these connectors are not UL or CSA listed, they provide dependable moisture resistance and electrical integrity in non-critical, indoor, or protected applications.

Used extensively in trailer lighting kits, automotive repair, and other custom wiring installations, tap connectors deliver fast, tool-friendly connections that can save time and effort. Their grease-filled, moisture-blocking design reduces the risk of corrosion, ensuring a more secure and lasting connection. With an easy snap-on design and support for multiple wire gauges, tap connectors are a must-have for electricians, technicians, and DIY enthusiasts who need a simple, effective way to splice wires with minimal effort.
