Morris Products UF Direct Burial Electrical Splice Kit – Includes Brass Connector, Heat Shrinking Tube – 14/3, 12/3 Min, 8/3 Max – Moisture-Proof Electrical Connection – Submersible, Raintight

The connector is good quality, but I ended up needing to purchase water proof electrical tape to finish the job. The heat shrink does not shrink enough even with a hot gun. Any hotter would have damaged the buried cable.

I have not used the product yet, but I have it on hand in case I need it. Basing from what I see in the kit, and quality of the materials used,I believe this spice kit will repair as good as if the wire had never been damaged. It will make a good waterproof repair.

I hadn't used a waterproof splice kit before, but I have to say that this was pretty easy. The four terminal connector was big enough for #8 stranded and the set screws in a brass tube provided a secure connection. After centering the shrink tube over the connector I used a heat gun on high setting and it took some heating time to shrink the pretty thick-wall tubing, but following the simple directions did the trick. Be sure to start heating in the middle, and around the entire connection, and work your way towards the ends AS IT SHRINKS. Don't be afraid to apply quite a bit of heat...at first I thought something was wrong because it took so much heat to even start to shrink, but once it started is shrank pretty fast. I was used to much smaller, lighter and thinner shrink tubing. As I worked to the ends, I noticed a bit of adhesive bubbling at the very ends of the tubing, which is good...means a positive water tight seal. It may be be quicker to use a torch with a flame spreader, but ultimately the heat gun set on high and a little patience worked fine.

If I ever need another one I will order it for sure

Works pretty well. It requires care in prepping the wires and patience with a heat gun on its high setting, starting from the center and working outward to each end in succession. I used liquid electrical tape before shrinking the sleeve and self-fusing tape afterward as additional precautions before direct burial. It is less durable than the original UF Romex if hit by a shovel, so if it will be in a landscaped bed, tuck it against the foundation or bury it deeper than you might otherwise.

I feel like I did all the right stuff... trimmed & connected the 2 sets of underground wires together on the brass splice block. The block and screws seemed quality. I coated it liberally with Black Liquid Electrical Tape (sold separately)Slid the plastic sleeve in place, and hit it with the (Harbor Freight) heat gun. Heated it center to outside edges, then back & forth as the tubing shrunk around the splice - so far so good... Once the tubing shrunk down tightly, I concentrated the heat for another 10-15 minutes but never got the contents to melt & flow out the ends of the tube. At that point I couldn't check the tubing to see if there was ever anything "meltable" inside of it. I just coated the ends a few times with the Liquid Electrical Tape and called it a day. II'll never know if it didn't work until it doesn't work...

The product works well but the heat shrink is very difficult to melt. Even with the heat gun on the highest setting it took a long time to melt and it did not melt evenly.

Apparently the way this is supposed to work is that the heat shrink tubing is supposed to swell up and get thick as it shrinks. This is what is supposed to seal the ends to keep out moisture/dirt. It did do that, but not enough. Using it with 14/2 w/Gnd UG cable, a noticeable gap was left at each end. I had to finish sealing the end with silicone sealant. Kinda defeats the purpose.The other problem is that one set of set screws on the 4-barrel splice coupling were so badly machined that I could not turn the screws in enough to grip the conductors. And we're talking about a decent amount of effort. I only needed to make 3 bonds so I lucked out. Had I needed to make 4 connections, it would not have worked.My own experience with other products beside this one suggests that the Chinese are not too good at machining threads.

I used this to extend the buried electrical connection after relocating my back yard shed. It's relatively pricy for what you get but I was unable to source a similar product locally. I used a heat gun on the heat shrink. I would have felt better if it would have shrunk a bit more around the exterior wire sheathing. It shrunk to a nice snug fit around the but end splice connector itself. I also would have preferred that it be a little longer. It was long enough but barely. The but end connector seemed to be of good quality. Over all I'm happy with the purchase. I feel like I'm unlikely to have problems with water getting into the connection any time soon.
