## Questions & Answers

**Q: suitable for r410a? suitable for 100 micron vacuum? weather resistant? ok to braze connections?**
A: Yes for 410a, we pull down to 500 micron vacuum, and they hold, pulling down to 100 should be douable just will take a while. For 410a we braze connections, very few crimp connections I trust at that pressure.
