## Questions & Answers

**Q: is this oil resistant**
A: It's made fore radiator. As far as oil on the outside it is silicone which has a surface that I would say oil would not stick but if it did it would wipe off easily

**Q: What is the bending radius?**
A: According to the information that is posted on this link it is
https://www.amazon.com/gp/product/B07PYZNRH9?th=1

 BEND RADIUS 5 TIMES THE HOSE OD ·

**Q: can this be used as hot water hose?**
A: Yes, it can be used up to 350 degrees F

**Q: So what size is it? You have it listed as 5/8” , but in the description it says 1/4” inside diameter & .58 outside diameter. That would make this 1/4”**
A: 5/8 hose
