Item Details

  • Stay Brite® can be used with all metals, except aluminum. Its low temperature solder is excellent for many HVAC connections.


  • Lead-free tin-silver solder kit
  • Produces strong, ductile connections on copper, brass, steel and stainless steel
  • Bonds with all the ferrous and non-ferrous alloys, except aluminum
  • Soldered joints exhibit considerably higher than necessary elongation for sound, dissimilar metal joints and vibration applications
  • Its low temperature and rapid melting characteristic, promotes capillary flow and less base metal distortion and oxidation, ideal for many HVAC connections.
  • Yields an overall component that is stronger than brazed components, whose base metals are weakened by annealment from high brazing heat
  • The melting range makes it suitable for soldering connections with a wider clearance.
  • Solidus: 430°F (221°C)
  • Liquidus: 535°F (279°C)
  • Shear strength (copper lap joint): 10,600 psi
  • Silver color is a good color match to stainless steel applications
  • Kit includes: 3/64" solder wire and 1/2 oz. Stay-Clean® flux
  • Made in USA


  • Joining copper, brass, steel and stainless steel
  • Used in residential HVAC applications
