## Questions & Answers

**Q: How well does it hold its shape on its own?  Good enough to flex and bend for a lathe?**
A: I would say yes. I do not have a lathe but have 2 of these on my bandsaw. They both expand and contract well but hold their position or shape where I put them.

**Q: Is the I. D. 4"? Will it fit over a 4" tube?**
A: Yes, the ID is 4” and it will fit over the OD of a 4” tube, connector, or adapter.

**Q: How long is this hose? This ad doesn’t say!**
A: The ad indicates 12" to 36".

**Q: What are the inside measurements?**
A: The inside diameter is 4".
