What Is Brazing for HVAC?

Brazing, similarly to welding, involves the process of melting and joining via a heated torch until the surface becomes molten and solders together. When it comes to HVAC, brazing is often used to join copper pipes, which are used to transport the refrigerant liquid. Brazing is a joining process that uses either hand or torch brazing methods, both of which require dangerous chemical compounds.

SmartLock aims to provide a more efficient and safer way to connect refrigerant lines by eliminating the need for brazing. If you are in search of an HVAC fitting that can connect refrigerant lines without brazing, we recommend the use of our SmartLock HVAC/R fittings. Get in touch with us today to learn more.


Why Brazing Is Not Ideal

The problems associated with brazing range from being expensive and time-consuming to being hazardous for workers and the environment. Here are a few reasons why brazing is not an ideal solution for connecting refrigerant lines to HVAC fittings:

  • The process of hand brazing often takes a long time and it requires a high level of skill.

  • A weakened brazed joint may lead to leaks and poor performance.

  • Brazing offers no real protection for the refrigerant lines, which could leave them unprotected from the outside atmospheres, such as humidity or heat.

  • Liquid from the line could leak from the brazed joint into the fitting, which could lead to refrigerant being in the air.

  • The brazed joint could fail over time because of freeze and thaw cycles or the effect of pressure changes.

By choosing a brazing-free refrigerant HVAC fitting, such as SmartLock, you eliminate these risks and more that are often associated with the brazing process. Get in contact with our team today to see if SmartLock is the right fit for your space.

How SmartLock Works

SmartLock is able to connect refrigerant lines without brazing thanks to our patented metal-to-metal sealing technology. Compared to o-ring sealing methods, metal-to-metal sealing allows for the highest design pressure range on the market. Plus, SmartLock uses metal ferrule, which is the most durable and stable material that is compatible with all types of refrigerants and tubes. Because of this, metal ferrule also extends the lifespan of the HVAC fitting itself.
