PMA Preforms

Brazing preforms are custom shapes designed to fit into many different physical configurations to meet specific applications.  They come in many shapes and sizes, such as washers, rings, balls, discs, shims, formed wires, arc rings and irregular shapes.  The size of the preform is determined by the area it is being used to join and the material desired.

All preforms are custom engineered and manufactured. Please call Rankin PMA at 800.845.7259 or 909.483.3222 to discuss preform options, or contact us at
