## Questions & Answers

**Q: What is the psi rating for this hose? Several commented that it is breaking. Perhaps the psi rating is lower than the pump they are using.**
A: While I don’t know the actual rating, I have had no problem with over 100’ of hose hooked to a diaphragm aerator 15’ deep in our pond.

**Q: Does this hose use "lead" for weight, or is some other high molecular weight material used?**
A: Thank you for your question. As the material density is 1.4g/cm3, the water density is 1g/cm3. So the hose can be self weighted.

**Q: 3/8 inch internal diameter or external diameter?**
A: 3/8 inch inside diameter. 3/8  barred fittings work well with this tubing

**Q: What is the pressure rating ?**
A: Thank you for your question. High strength material compound is extreme temperature Safe (-120° - +175°) temp rating for residential or commercial use.
