    I have used the 0% silver stuff called silvabraze. You have to get the tubing hotter and it doesn't flow like 15% but it works ok. I never had a leak. It does not stand up to heavy vibration like alloys with silver so I wouldn't use it on big commercial units. Is fos-flo 7 a Handy&Harman product?
