PTFE seal is the core of hydraulic equipment and the guarantee for normal operation of hydraulic equipment. Therefore, the installation of PTFE seals is very important. Any error in the installation process may affect the sealing performance, and then affect the normal operation of hydraulic equipment. Therefore, it is necessary for operators to understand the installation precautions of PTFE seals before installation. In addition, the storage of PTFE seals before installation should also be done in place.

Precautions for installation and storage of PTFE seals:

1. Check the relevant surfaces of the piston, cylinder barrel and installation guide sleeve, and ensure that they are clean and free of burrs and edges.

2. The installation tools shall be smooth, without edges and sharp corners, so as to ensure that PTFE seals will not be damaged in any form during the installation process (special installation tools for PTFE seals should be used).

3. During installation, a small amount of grease can be applied to the PTFE seal and the relevant surface of the cylinder barrel to facilitate installation, but no grease is allowed to remain between the rubber elastomer and the sliding seal ring, otherwise the sealing performance will be affected.

4. Whether installed vertically or horizontally, the coaxiality of the piston and the cylinder barrel should be maintained. Excessive eccentricity is likely to damage PTFE seals.

5. The installation speed should not be too fast, otherwise the PTFE seal will be damaged.

6. Storage of PTFE seals: during storage, PTFE seals should be put into sealed moisture-proof plastic bags such as PTFE, and the storage date and other records should be made, and then stored in a dark place to avoid poor storage and storage such as high temperature or direct sunlight, which will reduce their sealing performance.
