When we first got started as a company, we saw many issues with using open flames on expensive equipment to connect the valves to copper or aluminum tubes for any HVAC/R equipment. Not only were the flaring or brazing jobs causing inconsistent results that depended on the skill level of the contractor, but a hazardous job if the contractor had to use open flames in dry attics or in tight corners. Lets not forget the multitude of equipment and permits that are required for the traditional brazing and flaring work. Enter SmartLock: the global solution to all your HVAC/R problems.
