Earlier, we discussed that PTFE filled with carbon fiber（CF） and graphite is applied in the sealing industry, particularly suitable for complex working conditions. Today, we will explore PTFE filled with CF and MoS₂, which is also suitable for harsh working conditions such as high temperature and high pressure. Moreover, this new formula has greater advantages in dry and dusty environments.

Hydraulic five-combination seals are commonly used for piston sealing in hydraulic cylinders. They typically consist of the following five components:
