Review: 5.0 out of 5 stars: Professional-Grade Waterproof Splicing Made Easy! - When dealing with underground electrical splices, you absolutely cannot afford to cut cornersβ€”you need a permanent, waterproof, and durable connection. This Gardner Bender HST-1300 Underground Cable Kit is the gold standard for getting the job done right the first time. The key to this kit is the combination of its components. The Heavy-Wall Heat Shrink Tubing provides an incredibly robust, watertight seal that will withstand moisture, corrosion, and the toughest outdoor conditions for years. Coupled with the high-quality Screw Splice Connectors, this kit handles a wide range of common wire gauges, from 14 AWG up to 8 AWG, making it versatile for everything from landscape lighting to buried well pump cable repairs. The process is straightforward, yielding a result that looks and performs like a professional installation. After connecting the wires with the screw splices, applying the heat shrink creates an impenetrable barrier. This eliminates the annual worry of splice failure and ensures electrical safety in the trench. For any outdoor wiring project that requires a splice that will be buried, this kit offers unbeatable quality and peace of mind. Review: Good kit, but you may want to use some extra heat shrink for smaller diameter wire - I used this to repair a buried power cable that I accidentally hit with an auger bit when installing some vinyl fence in our garden. I had patched it years ago using some silicone caulk, but over time the caulk had cracked open and let water get into the connection, which started tripping our GFCI receptacle. After reading other reviews of this kit, I was concerned that the included heat shrink was too large for my wire (either 12 or 14 AWG--I'm not certain), so I did use some smaller, glue-lined marine heat shrink tubing (not included in the kit) to build up the thickness of the wire so the included heat shrink would have a larger diameter to grab onto. After doing that, the included heat shrink closed onto the ends adequately, and i could see the glue oozing out, which let me know I (hopefully) have a good seal that will last for many more years. ## Features - The product is good to use - The product is highly durable - Manufactured in China ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | GB Electrical | | Part Number | HST-1300 | | Item Weight | 1.6 ounces | | Product Dimensions | 1.25 x 4.5 x 12 inches | | Country of Origin | USA | | Item model number | HST-1300 | | Is Discontinued By Manufacturer | Yes | | Size | 14-8 AWG | | Color | Black | | Style | UF Splice Kit | | Material | Plastic | | Item Package Quantity | 1 | | Included Components | Gardner Bender HST-1300 Underground Cable Splice Kit for Waterproof Splicing, 14-8 AWG, UF Copper Wire - Includes: 8 inch.

I had patched it years ago using some silicone caulk, but over time the caulk had cracked open and let water get into the connection, which started tripping our GFCI receptacle. After reading other reviews of this kit, I was concerned that the included heat shrink was too large for my wire (either 12 or 14 AWG--I'm not certain), so I did use some smaller, glue-lined marine heat shrink tubing (not included in the kit) to build up the thickness of the wire so the included heat shrink would have a larger diameter to grab onto.

Perhaps they've just not worked with heat shrink tubing much? I ordered three of these to do code-compliant splices of a 10/3 run, a 14/3 run, and a 14/2 run ... all of which exceeded 250 feet and, thus, needed to be spliced in order to use standard cable rolls instead of purchasing it by the foot. I took my time and was in no hurry with the splices. I elected to do the 10/3 run first since it would need the least shrinkage on the tubing and I could take my time to gauge how much heat could be applied safely. This stuff begins to shrink around 200F, but you must heat a fair amount of it to get it to begin to shrink. I used an electric heat gun with temperature control on it and found that by setting the gun at 600F and holding the nozzle approximately 1.5" from the tubing and fanning it back/forth along the tubing in 3-4" wide strokes, I could get it to shrink fairly readily. I heated 1/4 side of the outside of the tubing cylinder ... starting in the center and working outward to the ends. Once that quarter section had shrunk, I did the next quarter section ... then the third quarter section, then the fourth -- each time working from the center of the tubing, outward. I shrunk it in stages, too ... meaning I didn't try to get maximum shrinkage in each quarter; instead, I shrunk it a bit at a time for all four quarters of the cylinder ... and then re-shrunk it again. I did this to promote even-ness in shrinkage along all quarters ... to avoid holes or weak spots in the tubing. Since I was being careful and trying to find the correct temperature to use with my gun on this tubing, the first use of the heat gun took ~10 mins ... on the largest of my wires. However, once I had a known good temperature, I was able to shrink the others in ~3 minutes after putting the splice hardware in place. I had no issue with the 14/3 or the 14/2. The tubing shrunk enough for it. Key to this was the adhesive inside of it, which melts. I made sure to wear insulated leather gloves during the heating process so that as I was finishing up the shrinking of the tubing I could squeeze it together and feel the adhesive flow and set -- making sure there were no open air pockets or bubbles in the adhesive (that could result in easy puncture points later, during or after burial). These kits served me well and I will buy/use them again if I need to make code-compliant underground splices in the future. ## Frequently Bought Together - Gardner Bender HST-1300 Underground Cable Kit for Waterproof, 14-8 AWG, UF Copper Wire-Includes: 8 inch.
