Why 50% of All Crimp Electric Connections Fail - One Trick Fixes It

A properly crimped terminal is what is called gas tight meaning the metal of the terminal is compressed hard enough on the wire that oxygen molecules can't get between the terminal and wire. If not crimped properly oxygen can penetrate and oxidize the metals causing corrosion. 99% of DIY crimps fail because wrong size terminal or wrong tool doesn't make a proper mechanical gas tight crimp.

Proper terminals, you mean Scotch Locks?

For anyone who may have a Panduit ratcheting crimper with a cracked frame near the dies, Greenlee bought the company and hopefully, they still cover Panduit, but I called to find out what they do about the crack- they sent a Greenlee replacement without the dies, which are still interchangeable.
