## Questions & Answers

**Q: Which on will work for labeling coax rg-6?**

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.

**Q: 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?**
A: 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.

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

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