If you go to this page: http://www-public.tnb.com/ and look at the upper right hand tabs you'll see Distributor. Click that tab and in the next screen use the second way (T&B Distributor Listing) to get distributors within your zip.
Update. None of the distributors carry the T&B wire nuts. I had to do a special order for the 335C (8 to 18 gauge). The smallest quantity seems to be the cards (6 per card) with a 20 card minimum order @ ~1.30 per card.
I can only say every connection I have ever come across is a steel spring wirenut that's usually totally rusted. My goal is to improve on what seems to be accepted practice of using wire nuts for low voltage outdoor circuits.
Ideal sells 'set screw wire connectors'. These have a brass sleeve with a brass set screw on the side. You insert the wires into the sleeve, and tighten the set screw. Then the whole thing screws into a plastic cap.
Yeah, I'm familiar with those, used them alot in class1 div 1 locations...
Although I'm not fond of the comparitively weak plastic cap for the nut - as it is essentiallty just a container of silicone with a spring connector in it, and if a brute like me, they can crush in your hand... But they do work well for the purpose. For the longest time they were the only patent holders for this type of application. Now a few others are making them too. Havent use these yet though... http://www.idealindustries.com/wt/TwistOnWireConnectors.nsf
