## Questions & Answers

**Q: Will these 'uy wire to wire connector k1' work with 18 awg wire?**
A: These are designed to be used with 26awg telephone wire.  It is unlikely that you will be able to use these for 18 awg wire.  Amazon sells the following products that should work for you:

or
https://smile.amazon.com/MUYI-Connector-Insulated-Electrical-Connectors/dp/B075S6PJTK

I use the latter, most often, however, it takes a crimping tool to get the best connection with these.
Good luck with your project.

**Q: Are they gel filled?**
A: yes

**Q: Will these work with cat6 wire?**
A: Will work with cat6.  Cat6 is only slightly bigger gauge wire. 
Cat 5 24-26 gauge vs Cat 6 22-24 gauge

**Q: Will these work for doorbell wire?**
A: yes this will work on door bell wires
