75 Pcs Ideal Al/Cu Twister #65 Purple Wire Connectors Copper to Aluminum

Great products for aluminum wire

Easy to use, but almost absurdly pricey. I know the certification process is expensive , but over two bucks each? I just decided to bite the bullet and do the job right.

Aluminum to copper connectors

Needed 75 for major project, received damaged packaging along with 20 missing.

Best value for your money!

Actually didn’t need them after all

I bought these to save money on an electrical upgrade. The purpose was to create a safety buffer between aluminum wires, on the advice of our insurance company. My electrician was very pleased with these caps because they come with the gel already in them. It saved him a lot of time, since all he had to do was screw them on. I don't know much about the subject, but I can give this product a thumbs-up based on the word of my electrician.
