3M 7000058827 Direct Bury Splice Kit 18-10 Awg

Product Description

The 3M 7000058827 is a direct bury splice kit designed to electrically connect and moisture-seal wire with thicker insulation in underground applications. Each kit includes a 3M Spring Connector R/Y+ and a high-impact, UV-resistant tube prefilled with moisture-resistant grease. The assembly creates a weatherproof, moisture-sealed splice rated for 600 volts, making it suitable for buried conductor connections in landscape lighting, irrigation controls, and low-voltage underground wiring systems. Licensed electricians and irrigation technicians are the primary installers. Wire range is 18 to 10 AWG, and each kit contains 2 splices.

This splice kit is suited for direct bury wiring applications where moisture intrusion is a concern, such as underground feeder runs, irrigation system wiring, and outdoor low-voltage conductor splices. The prefilled grease tube eliminates the need for a separate sealant during installation. UL-listed for direct bury service. Sold as individual kits; minimum order quantity is 25 kits per shipper.
