The nVent GARDNER BENDER HST-1300 Underground UF Splice Kit is the professional’s choice for creating dependable, waterproof connections in demanding environments. Designed specifically for direct burial applications, this kit simplifies the process of repairing or extending underground feeder (UF) cable. Whether you are working on outdoor lighting, power to a detached garage, or underground utility lines, this kit provides a permanent, secure solution. Engineering excellence is at the core of this underground cable kit. The included connector set screws engage each wire securely for a solid splice, eliminating the risks associated with loose connections in buried lines. To ensure total environmental isolation, the kit features an 8-inch heavy-wall polyolefin heat-shrink tubing. This tubing is lined with a specialized watertight adhesive that melts and flows during the shrinking process, creating a moisture-proof barrier that protects your copper conductors from corrosion and failure. This versatile kit is built to accommodate a broad range of wire gauges, specifically 14 - 8 AWG UF copper wire. It is strictly rated for a maximum of 600 Volts and is compatible with a minimum conductor size of 14/2 with ground and a maximum conductor size of 8/3 with ground. Trust nVent GARDNER BENDER for high-quality wiring accessories that deliver application flexibility and long-term durability in the Industrial & Scientific and Industrial Electrical categories.
