Which on will work for labeling coax rg-6?

Hello, Thank you for your inquiry. The specific part referenced #M21-250-C-342 will work on the following. 3:1 heat shrinking sleeve designed for 16 - 8 gauge (diameter 0.094 - 0.215 inches, 2.4 - 5.5 mm). I hope this is the answer you were looking for. If not can you please re-state the question.

It says at the title that the width is 0.335" and in the specifications 0.187" (Im looking for the second one) but I have this problem with the specs?

This is a shrink tube. Total length is 7', tube width a little over a 5/16". I'm not sure what is .187" indicating.

Wich one of these is able to slip over the LC Fiber connector and shrink down onto the fiber patch cable?

Thank you for your inquiry. The M21-250-C342 has a starting diameter or 0.415" before shrinking. The correct tubing would depend on the specific connector.

will .335 shrink down onto a 18 gauge wire with jacket ?

Thanks for your inquiry. 3:1 heat shrinking sleeve designed for 22 - 16 gauge (diameter 0.046 - 0.11 inches, 1.2 - 2.8 mm). I hope this helps. If you need more information please let me know.

Great (expensive) product

This is a quality product and it makes my work look significantly more professional. If it were half the price, I'd give it 5 stars and order it by the case. Make sure you order the appropriate size for the gage of wire you're going to be labeling.

PermaSleeve Label

I received my Brady label as of October 7, 2025, it has a yellow color, fits perfectly for my Brady M210 labeller, I hope this will fit to any sleeve, I recommend buying this from Brady its quite pricy for a label but its genuine, you get what you paid for!
