Wirefy 150 Wire Connectors - Wire Butt Connectors Heat Shrink - Heat Shrink Crimp Connector for Wiring - Electric Marine Grade Connector Waterproof Butt Splice Electrical Kit

About six months ago I bought an assortment of Wirefy electrical connectors to re-wire an antique tractor for a customer. I had never used this brand of wire connectors, but found that they work well. I was impressed enough with Wirefy connectors that when I ran out of the 14-16 AWG Butt Connectors I ordered this refill. The connectors are of good quality, crimp easily, and the heat shrink tubing shrinks evenly and bonds to the wire insulation well. Again, I was impressed, and by-the-way, so was my customer! I'll be shopping Wirefy for my wire connector needs. (Note: This is not a paid endorsement, nor do I know anyone associated with Wirefy; they just make and sell good wire connectors!)

Good option for cheap if you do a lot of splicing. Get the job done and better quality than standard garbage at home depot.

I’ve been using these connectors in a damp marine environment, and they’ve held up just as well as some of the higher-priced options I’ve tried. They crimp cleanly, the heat shrink tubing seals tightly, and I haven’t had any issues with moisture intrusion. I appreciate that each connection feels secure once heated, giving me confidence in long-term durability. For the price, the performance is excellent, and they’ve become my go-to choice for boat wiring projects. .

Very good connectors, they crimp and shrink very well used them indoor and outdoor situations no issues. I ran these underground - direct burial and they have lasted over a year for powered speakers.

They work! Much better than most.

Great connectors. These butt connectors are very high quality. With good heat shrink. They are a must if you want high quality secure connections. Pair them with the crimpers by the same name and there is now equal. I have used thousands of connectors and crimpers and these by for are the best.

They do the job for crimping wires together.

After many hours of reading I am using this to make waterproof butt stranded copper low voltage 12V wire junctions which are permanent. The Connector is heat shrink but filled with adhesive: raising the joint to heat shrink the tubing also liquefies the adhesive so it oozes out a bit and fills the small space (easy to see the adhesive filling the gap). Cooling solidifies the adhesive. The cable will be buried but I have tested it at home in water for a few months without any sign of failure.
