Muy resistente y duradero!!!

Vraiment bien

I had bought a container of 1000 of these wire nuts years ago and have used them extensively in my job of heating and cooling repair. I love these nuts. :D They work very well with many different sizes and types of wire from stranded 10 gauge to solid 22 gauge and any mix thereof. They hold tight and grip well and the blue rubber skirt gives extra protection against shorting and electrocution. They easily screw onto various sizes of wires and come off again cleanly if needed. Made by 3M so the expected quality is there and they hold up well in all climates from 112º to -10º, from the blistering sun to the damp crawl space under an 80 year old 3 bedroom. When I started to run out a couple of months ago I went looking for more only to find that I could not buy them anywhere local. Was facing the prospect of having to use those inferior cheap plastic wire nuts that I have come to hate for their ability to rip the small wires in two under their caps and their equally frustrating ability to not screw onto the big wires no matter how hard I tried to get them to "take". Went looking online for these wire nuts and found them on Amazon. Bought two boxes hoping they were the same quality wire nuts that I had bought nearly a decade ago and waited for them to arrive. Two days later I received them and opened the box, I was elated to discover that yes, they are the same product that I have come to love and that the price was reasonable for such a fine piece of workmanship. Don't laugh, you cannot understand what its like to crawl under a house at 2 am on Christmas eve, dragging your tool bag behind you as you inch your way towards the non-functional furnace that is sitting 40 feet away from the entrance, only to discover that the crappy wire nuts you have in your tool bag will not screw onto the wires and now you have to crawl back out for more and redo it all again. Let me just say that I have probably invented a few new words as I made that trek. Long story short, these wire nuts from 3M just work. I will be buying a few more boxes.

Es muy útil para empalmar alambres de manera segura y fácil.

I have been using these 3m wire nuts now exclusively for several years. Because of the way they internally coil, they hold wires very securely. I have become a wire nut snob and replace all other wire nuts on sight. One very confusing thing when switching to 3M was that I did not understand the difference between the O/B+ and the T/Y+ nuts. I had to order both kinds to compare them. They are flat out identical and have the same specifications of wire sizes they work on. I have to assume there is some regulatory callout somewhere for the colors that force them to make them in both color combinations. I find myself using these small ones the most often in residential wiring as they take up very little space in electrical boxes. They are rated for up to three 12 gauge conductors.
