Reflok connection strenght
Reflok connections withstand 10 x higher pressure than the pressure in the high pressure system using R410A, in which the pressure reaches 44 bar.
These connections are also used in high-pressure CO2 systems where working pressure as high as 120 bar.
Mechanical testing of Reflok components - in this case a stretch test to failure..
As you can see the pipe cracks and the connection is still stable.
