In my case to ensure tightness in the threaded joints I put enough Teflon tape and oil paint so that the thread is impregnated, tight and ready !!!, it is a very good practice to be sure that the pressure gauges with which Work in refrigeration are calibrated and treat them with special care since their internal mechanism is very sensitive and prone to be descalibrated by blows and bad handling (something very common in some technicians), I have my gauges in a separate box just for them, and the padded box inside, regards
