how much SF6-Air leakage and quality

Nov 19, 2015There are two causes of AC system leaks – age and moisture. While much of your air conditioning system is made of metal, including the high pressure lines, rubber is still used throughout. You have rubber O-rings, grommets, lines and more. The problem here is that rubber degrades over time and with exposure to heat and moisture.
