## Questions & Answers

**Q: is this 1" inside diameter??**
A: The corrugated portion is 1" inside diameter.  The short (about 1.5") tubular portions before the nuts are  7/8"

**Q: what the burst pressure rating and time?**
A: I do not know the exact specifics about the hose.  I can tell you I have had the line under about 30-50 psi for about 8 months and all is good. Very strong stainless and well constructed.  Fairly flexible. I am using it on a water softener on a water well.  Good luck!

A: At this moment we do not have data available for this flex line.

**Q: Is this for one or a pair?**
