Lucas-Milhaupt Sil-Fos® Rings for brazing copper tubular components. Braze rings are easy to use, minimize waste, and provide visual verification of a complete, sound braze joint.
Sil-Fos Rings are a brazing alloy composed of 15% Silver (Ag), formed into rings to fit inside the flared fitting used to join copper tubing and fittings (commonly used in HVAC/R systems). When properly heated, the rings create a tight, leak proof joint.

ApplicationBest alloy for general copper-copper brazing in the Sil-Fos family. For copper-to-copper joints the phosphorus in the Sil-Fos product serves as the fluxing agent and no separate flux is necessary. For brass applications, however, flux is recommended. For use where close fit-ups cannot be maintained Sil-Fos 15 works well to "bridge" gaps. Highest joint ductility of the entire Sil-Fos family to best withstand the stresses inherent in refrigeration applications. Slow flow.
