Joining solutions built for HVAC/R copper work
In HVAC/R, a leak-free joint is everything. From line set installs to refrigeration repairs, Harris Products Group® provides professional-grade brazing alloys, solder, and flux engineered for dependable flow, strong bonds, and consistent results in the field.
Brazing is commonly used for higher-pressure refrigeration systems and copper-to-copper connections, while soldering is often used for plumbing/low-temperature applications. Selecting the correct alloy and flux helps improve wetting, reduce oxidation, and deliver a clean joint with fewer rework hours.

Harris Brazing & Soldering — FAQs
When should I braze instead of solder?
Brazing is commonly used for refrigeration/HVAC copper joints that see higher pressures and temperatures. Soldering is typically used for lower-temperature plumbing applications.
Do I need flux for brazing?
It depends on the alloy and joint materials. Many HVAC/R copper-to-copper brazes are done without flux, while copper-to-brass or certain alloys may require it.
What info do you need to recommend a rod/alloy?
Share the application (HVAC/R vs plumbing), tube size, joint materials (copper/brass/steel), and whether you prefer flux-coated or separate flux.
