You know I had to look it up before patching my radiator in my car.. I can't remember now.. Ohh the joys of old age are creeping in.

Old senile biker.. hey babe, who are you? (to wife) can I buy you a beer? Can you see me sitting in the sunshine in a old folks home, fan in front of me blowing my long beard over my shoulder, a nurse making vroom vroom sounds in my ear..

Braze with 15% silver solder, no flux. Soft solder is not allowed in most places due to potential leaks.

The stuff used is called sil-phos. Its really picky about temperature.

15%silver sil-phos is what we use. Heat evenly and it will suck in completely and seldom leaves pinholes. Who ever pumps the system down will find any leaks. Should hold 300 microns for 15 minutes or so.
Good luck.
