King Tiger BCuP-2 — Copper-Phosphorus Brazing Rod (AWS A5.8 BCuP-2)

HAKUDO BCuP-2 is a copper-phosphorus brazing rod for copper-to-copper joints — self-fluxing (7% P) so no flux is needed on copper. The standard filler for refrigeration, air-conditioning and copper pipe.

Best for: HVAC and refrigeration copper lines, evaporator/condenser coils, water and gas copper pipe, electrical busbars and connectors, copper plumbing fittings. (Use flux for copper-to-steel; not for > 10% Ni alloys.)
