Gardner Bender HST-WP Well Pipe Splice Kit, 14-8 AWG

I had a certified electrician (family relative) install this for me, and everything with the underground electric worked after he was done. Roughly 6 months later, I lost electric to my barn, dug this splice up and there was water in it.I asked the person who installed it why it failed, and he said because it's junk. I asked him why did you install it then, and his response was because you told me to. I felt like I was talking to the the T-800. Needless to say, I found a new electrician who repaired the underground splice the right way. I can't say exactly what he did/used other than he had a container of liquid electrical tape. The new and improved electrician, I'll call him the T-1000, agreed with the other guy that these kits rarely hold up.

1. The set screws are tiny and easily strip.2. The heat shrink tubing is thicker than a garden hose and REQUIRES a strong heat gun, or it will not shrink at all.3. It does not actually shrink enough to make a water tight seam, and if you keep trying it just burns.4. RETURNING it with chunks of wire attached so they see how bad their product performs.

i was disappointed--I THOT I WAS BUYING A KIT TO SPLICE MY WATER PUMP WIRES.THIS IS FOR 1 (ONE) WIRE--I WOULD NEED 3 FOR MY 220V PUMP.THAT WOULD MAKE THE TOTAL COST OVER $24. NOPEI ORDERED ANOTHER KIT WITH 4 CONNECTERS AND HEAT SHRINK TUBE FOR $8.THE WORD "KIT" FOOLED ME.

So if you have 6/2 with ground UF-B this will only work if you are willing to "cheat" a little. A 6 gauge as-is absolutely will not fit into the coupling. The 6 gauge I used was made up of 7 strands so I cut one strand off to make it fit. Yes, I know, now its no longer a 6 gauge but I figured the brass coupling would make up for the difference. Note that the primary Amazon photo as of 1-10-20 is a bit misleading since it does not make it clear that you get 4 couplings and a plastic holder for them (just to be absolutely clear, this is for the HST-1300 - you get 4 brass couplings, all of which fit in the one plastic holder which is X shaped so it holds all 4 couplings - in my case I only used 3 of the couplings). My photos are from what I received 3 days ago. What I did probably wouldn't pass a strict electrical code inspection but I'm confident it is much better than the 10 gauge RV hookup wire I was using.

Written by my husband.As others have noted, once the heat shrink is shrunk it is too large. So, here are some specifics that should have been included in the product description. The brass connector block is about 23mm (15/16") diameter. The pre-shrunk inner diameter of the heat-shrink tube is about 34mm (1 and 15/16"). The post-shrunk inner diameter is about 9mm (3/8"). A 14/2 UF cable is rectangular(ish) in shape about 5/16" x 3/16". So, the post-shrunk size is just a little too big to make a water tight seal on a 14/2 UF cable. What I did, was I purchased another heat-shrink tube and shrunk it onto the UF cable first. This tube was: http://www.amazon.com/gp/product/B007Z3ZEJW which has a pre-shrunk I.D. of 3/4" and a post-shrunk I.D. of 2/16" but its wall thickness gets as big as 2/16" as it shrinks. So, on the 14/2 UF cable, once this tube was shrunk, the 14/2 had an approximate O.D. a little over 1/2". This enabled me to shrink the tube of this kit onto the other tube making a water tight seal. If you do this, make sure this kit's tube (the larger tube) overlaps the smaller tube by several inches but does not completely cover the smaller tube (a few inches of the smaller tube should still be visible).

Used splice inside service entry to extend length of wires from stove breaker, and permit moving breaker location in panel necessitated by installing interlock for emergency generator breaker. Splice kit provided absolutely positive splice from captive screws with low "volume" added in the panel, and sealed for corrosion prevention with the heat shrink material provided. Fantastic product for making service wires longer, even inside a service panel!

I have a 55 pound thrust newport trolling motor that I wanted to add 6' of cable to. The wires I got for the extension were thicker than the wires coming off the trolling motor, but this system worked well and clamped to both together without issue. The heat shrink worked well and sealed down tight although took a longer than I expected to get hot enough due to its thickness.

A great concept... takes a little finesse to get the wires in the slots all at one tine, but doable. I found that putting one set in, tightening them as you go, then trying to get the other set all in at once worked ok. Don’t forget to slide the sleeve on first! Also, the brass joints are removable if you need to slide the out. I used a heat gun to seal... took longer than i expected, but a great seal.

Just what the doctor ordered

Best (only) kit for this type of cable. Have used for years, no failures as far as I know.

Ça fait la job!

worked good
