## Questions & Answers

**Q: My 10+ year old s-715 hisses, even after installing new s-727 plugs. does the very small o-ring in this s-715 eventually wear out?**
A: Yes, orings can get old and less plyable so they will not seal as well

**Q: is this for high pressure propane on an RV tank?**
A: The model number S-715 will be an air style fitting. The maximum pressure will be 300 PSI.

**Q: Where is it made?**
A: Mine says made in USA on packaging. Nothing listed on the part itself. I like mine, purchased several and all work good. Would buy again.

**Q: If a single pack costs $4.68, why does a 2 pack cost $16.99 ??**
A: Better quality  or greed
