Rubber o-ring leakage problem is inevitable, we can do is to minimize leakage, then the impact of rubber o-ring leakage factors have those?
 
1, rubber o-ring quality is not qualified.
 
2, rubber o-ring aging serious.
 
3, rubber o-ring installation is not qualified.
 
4, rubber o-ring formula is not qualified.
 
5, mechanical equipment sealing design is not qualified.
 
6, mechanical equipment trench size and quality problems.
 
7, the oil temperature is too high, resulting in rubber o-ring wear, aging and even failure.
 
8, the pressure is too high, resulting in o-ring is squeezed out.
 
9, lubrication is not in place, or the use of solid lubrication, resulting in rubber o-ring is worn.
 

10, the medium and oil liquid has impurities, is contaminated, resulting in rubber o-ring wear or corrosion.
