Junction Box Outdoor 2 Way Waterproof IP68 Electrical Cable Connector,M16 Wire Range(3.5-10mm),Suitable for Repair and Extend Power Cables,UL(5 Pack)

However, they are easy enough to take one side apart if needed once in a while for service. They are waterproof and are well made. Think of them as a reusable Butt connector but without the need for crimping. Screw tightens clamping on wire strands. Tin the wire will make it easier but not really necessary.

Well built and perfect to extend the line between my low power solar lights and panel. Very well built easy to use but pay attention to not invert polarity when using for DC CONNECTIONS.

I love these. I have a habit of accidentally hitting extension cords with the snowblower or lawnmower.... these are a great waterproof solution to repair them when that happens or join 2 cords in a waterproof way rather then plugging them end-to-end.I have used them on outdoor 16 ga (16AWG) cords; not sure if they work on larger ones.

My first time using one was a learning curb. I cut the wires too long and stripped the wire too long. It was easy to just cut the wire shorter and try again. I still had too much wire and had to just cut shorter a second time. The amount of wire used in the connection fooled me. Be prepared to try again.

I used this to connect a new water pump on my outdoor fountain. The cord is continually wet and haven't had an issue since install which was approximately a month ago! Sealed very well!

I used these to modify some LED pool lights that only came with 50 ft cables. These use R/G/B with return which worked well with the 4pin configuration. A smaller version would be great as I was concerned about these fitting through all my conduit joints. These did fit fine. The waterproof feature was a "must have" for me as part of the conduit run is below water level.

fits 2 wire 12 gauge romex beautifully.

Item was supposed to include 10 small rubber rings, however six or only included
