What is the maximum resistance to the seal in the hydraulic system currently being produced?
With the ring to 30MPa, if you use a triangular sealing structure (similar plug root) can be used in 70MPa.
The key depends on your seal structure, the good sealing structure can assist the seal, reduce the pressure of the seal. Take a simple example: the well-known O ring, the static sealing pressure 5~10MPa
Therefore, in order to improve the sealing capacity, not only rely on seals, good structure is also very important. You say, if the light takes into consideration the seal, there is no problem with the regular 50MPa (usually around 30).
