3M Direct Bury Splice Kit DBO/B-6 (BULK), 18-12 AWG, UV-Resistant, Steel Spring, Flame Retardant Insulation, 1 pack containing 2 Splice Tubes and 2 O/B Connectors

3M Direct Bury Splice Kit DBR/Y-6 - Trying to connect three 12-gauge low-voltage wires together without the proper connectors is a pain. I've tried various dielectric-filled skirted wire nuts, and some work okay, but this complete solution is the best for me. The wire nuts that come with this are substantial. They fit the three 12-gauge wires and tighten securely. They were easy to grip with the protrusions on either side. The wire nut is guided by grooves on the sides of the dielectric-filled housing, and the connection is totally submerged. The end tab neatly separates the wires and locks in place. I can't imagine a better solution.I have and will use plain dielectric-filled wire nuts for joining a smaller diameter lamp wire to the end of a feed wire, but for splicing in another feed wire, this is the only thing I will use from now on. These are costly but worth it.

Always wondered what this was. But once we figured out and got this product, it took a few mins to replace the selonoid and connect it using this to the irrigation system.

Solved a long standing problem with burial of low voltage lines. Easy to use and seems very durable.

Glad I found these. Easy to use. Wires very secure.

Serves the purpose.

Easy to install.

Since you wire nut your connections and then immerse then in a gel within the tube, it makes a great seal against water. However, if you need to add a wire, add a light or trouble shoot the circuit, the gel makes a mess. Removing the wire nut from the gel tube removes the gel and it does not all go back in or cover the connection again.

Time will only tell how well these hold up, but as long as you bend wires into the three slots on top of the connectors, they snap closed well and seem quite robust. Easy to connect.
