DURA-IS Soldered Edge Tension Finned Tube

DuraFin Tube offers two distinct types of soldered finned tubing: root solder and solder-coated. Root soldering involves a special DuraFin Tube technique that uses enough solder to create the bond between the tube and the base of the fin thus avoiding bridging. Solder-coated finned tubing covers the entire fin and tube surface with the alloy. Lead-free Tin alloys are available for all soldered products.
