Why Surface Preparation Matters
Oxidation and surface debris on copper tubing can compromise solder flow and joint integrity, leading to leaks and callbacks. Using the correct size cleaning brush — like the B-925 for 3/8″ OD tube — ensures the mating surfaces are properly conditioned for a strong, reliable connection every time.
