KappFreeA™ - THE ACID CORED convenient one-step Lead-free Cadmium-free Potable Water Solder

Starting at: $24.50

KappFreeA™ Acid-Cored solder produces strong and ductile joints on Copper and Brass without requiring additional liquid or paste flux. The internal acid flux is released on heating to remove the oxide layer on the Copper and Brass parts. The resulting joints have good tolerance to vibration and stress, with tensile strengths to 10,000 psi on Copper. Learn More
KappFree™ - THE Lead-free Cadmium-free Potable Water Solder

Starting at: $15.00

KappFree™ solder is THE Lead-free Cadmium-free formulation designed specifically to replace Tin-Lead solders in Copper, Brass and Stainless Steel plumbing applications. KappFree™ provides less joint strength, vibration resistance and thermal cycle fatigue resistance than KappZapp™ solders, so is used less often in high pressure or very cyclical heat exchangers.

KappZapp3.5A™ Acid-cored Solder

Starting at: $24.50

KappZapp3.5A™ Acid-cored Solder is a convenient solder for most Copper, Brass and Stainless Steel plumbing and sheet applications. The center of the solder contains an acidic flux. When the solder is heated, the flux is released and removes the oxide coating to allow a strong bond to form. Learn More
KappZapp7R™ Rosin-cored Solder

Starting at: $35.50

KappZapp7R™ Rosin-cored Solder has rapidly become the audio industry standard for electrical / electronic Copper applications. The 7% Silver solder creates extremely clean conductive joints with high strength, ductility and corrosion resistance. The center of the solder contains a mildly-acidic natural rosin flux. When the solder is heated, the flux is released and removes the oxide coating to allow a strong bond to form. Learn More
KappZapp3.5R™

Starting at: $24.50

KappZapp3.5R™ is the most convenient solder for electrical/electronic connections between Copper wires and contacts. It melts completely at just 430°F (221°C). This minimizes the heat applied to your sensitive electronic parts and minimizes distortion of thin wire or tabs. The mild Rosin flux residue is removed with a wet q-tip or cloth. Learn More
Kapp Copper-Bond™ Flux 500°F - 750°F (260°C - 390°C)

Starting at: $10.00

Flux designed specifically to work with KappZapp7™ 7.0% Silver solder to remove the oxide layer on Copper to allow a strong metallic bond between the solder and the base metal. Its active range is 500°F - 750°F (260°C - 390°C). Learn More
Kapp Comet™ Flux - 350°F - 500°F (176°C - 260°C)

Starting at: $10.00

Flux designed specifically to work with KappZapp3.5™ and KappZapp4™ Silver solders to remove the oxide layer on Copper to allow a strong metallic bond between the solder and the base metal. Its active range is 350°F - 500°F (176°C - 260°C). Learn More
KappZapp7™

Starting at: $30.00

KappZapp7™ is an audio industry standard for vehicle and home theater speaker installations. Its 7% Silver content requires a higher temperature range, but yields superior strength and vibration resistance. Learn More
KappZapp4™

Starting at: $25.50

KappZapp4™ contains 4% Silver (Ag), and is often preferred for hand soldering Copper wires and tabs. It has a wider slushy or plastic range (430°F-475°F and 221°C - 246°C) to allow users to manipulate parts while the solder joint is cooling and hardening. Learn More
KappZapp3.5™

Starting at: $20.00

KappZapp3.5™ is the most popular of the low temperature Silver bearing solders. It melts completely at just 430°F (221°C). This minimizes the heat applied to your sensitive electronic parts and minimizes distortion of thin wire or tabs. Learn More
