Although I'm not looking to purchase any, does anyone know if the Ideal 65 purple wire nut is still being manufactured. I looked at the Ideal Industries web site and couldn't find them available. Did the wire nut lose its UL listing?

I found this on the ideal website:
http://www.idealindustries.com/pdf/Twister%20AL-CU%20Compliance%20Document.pdf

looks like they changed the color, though.

It's still on their site, a direct link is not possible.

Go to the Ideal site, chose screw on connectors than chose 'Twister' than scroll down and you will find them.

Yeah, you're right. They were right there.
