ENDIESS Underground Wire Splice Kit

600V Maximum Voltage & Cable Splice Kit
Engineered for versatile applications, these underground wire connectors support up to 600V, making them ideal for diverse electrical projects. Each premium-grade wire splice kit is perfect for repairing damaged underground lines with industrial-grade reliability.
Industrial-Grade Durability
Constructed with premium corrosion-resistant materials, our underground wire splice withstands extreme outdoor conditions (pool pumps, garden lighting, etc.). Engineered to meet industry standards for heavy-duty use and extended service life.
Space-Saving Universal Design
Heat shrink wire connectors with compact dimensions (supports 14/3 to 8/3 wire range) enable easy portability in tool belts or pockets. Ideal for confined spaces while maintaining full compatibility with standard UF underground feeder cables.
Four-Position Wire Connector
Easy to install—first strip 8–10mm of insulation, loosen the screws on the connector block, insert the four-core wire in opposite directions, and tighten each screw to completely eliminate the risk of false connections.
Professional-Grade Heat-Shrink Tubing Sealing
The cable glands feature heat-shrink tubing for a secure, weatherproof seal. Simply thread the wires through, then use a heat gun to shrink the tubing—starting from the center and working outward for a perfect, airtight seal.
