I would like to ask: what materials can be used as substitutes for the aging sealing rings at both ends that penetrate through the ground surface? Is there any remedy?

If the sealing rings at both ends penetrating through the ground become aged and damaged, the following materials can be considered for replacement or repair: 1. Rubber sealing rings: Rubber sealing rings possess excellent water resistance and wear resistance, and can be used as substitutes for sealing rings. 2. Polymer seal rings: Polymer seal rings possess excellent resistance to chemical corrosion and high temperatures, making them suitable for use in certain special environments. 3. PTFE sealing rings: PTFE (polytetrafluoroethylene) sealing rings possess excellent resistance to high temperatures, corrosion, and low friction, making them suitable as alternatives for sealing rings in high-temperature and corrosive environments. In addition to material substitution, the following remedial measures can also be considered: 1. Replace the seal ring: Swap the aged and damaged seal ring for a new one to ensure proper sealing. 2. Sealant: Use a special glue or sealant to repair the broken parts of the seal ring, thereby restoring its original sealing performance. 3. Sealing tape: Use special sealing tape for wrapping to improve the sealing effect. It is necessary to select appropriate materials and remediation methods based on the specific circumstances and usage environment; it is recommended to seek evaluation and guidance from professionals with experience in this area. .
