Horizons Brazing Rings are the cleanest and brightest, free of oxide and surface impurities. Horizons alloys are pure and shiny, and that cleanliness runs all the way through the rod. What a huge difference purity makes in the integrity of your brazed joint. Leaks are caused by oxide and impurities that enter the joint in the molten metal of an impure brazing alloy and impede the brazing alloy flow. Wherever there is contamination, the alloy flows around it, leaving pinholes in the joint. These pinholes are tiny doors which allow refrigerant gas to leak out.
