Easy to Install as 1, 2, 3

  1. Strip wires, apply the ScotchlokTM Electrical Spring Connector and twist in a clockwise direction.

  2. Insert the splice into the gel-filled insulator tube. Push past the locking fingers to hold the ScotchlokTM connector in place.

  3. Position wires in wire channels and snap insulator tube cover closed.



Saves Time

The 3M Direct Bury Splice Kit is a real time saver when installing underground electrical cable systems. Every component for the splice is included in the kit. The insulator tube is pre-filled, eliminating the chance of the installer using too much or too little sealant. No crimping tools, no waste, no mess. Just quick, reliable underground splices for projects of 30 volts or less.


  • The DBY splice kit meets a wire range of 2-5 #18 AWG through 2 #12's AWG solid or stranded copper wire.
  • The DBR splice kit meets a wire range of 5 #16's AWG through 3 #10's AW solid or stranded copper wire.
  • Sealant does not set up hard, allowing splice to be reworked, without cutting wires (new tube required).
  • Application Temperature Range: 32oF to 120oF (0oC to 49oC).
  • Storage Temperature: 120oF (49oC) maximum.


  • Insulating gel is already contained in the tube.
  • Long-term electrical properties reduce callbacks and rework.


  • Locking fingers in the tube ensure that the ScotchlokTM connector stays in position.
  • The closed tube cover provides strain relief.
  • Design protects against corrosion failure.
