3M Direct Bury Splice Kits hold and help protect electrical connections for direct burial applications. Each tube comes prefilled with moisture-resistant grease to reduce exposure to damp environments. They create a uniform hold for a reliable connection in demanding outdoor environments up to 221 F (105 C). Between the strong hold and weather resistance, 3M Direct Bury Splice Kits are ideal for golf course irrigation, landscape lighting, and direct burial splicing. Compliant with RoHS 2015/863/EU.
