**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?**
