I. Principles for Selecting Chemical Media for V-Rings
As an important sealing element, V-rings need to consider factors such as the working environment, chemical resistance, and cost-effectiveness when selecting chemical media. The following are some basic principles for selecting chemical media for V-rings:
1. Working environment matching: First, make sure that the selected chemical media matches the working environment of the V-ring. This means that the V-ring must be able to work properly in the expected temperature, pressure, and chemical environment, and will not degrade or fail due to contact with chemical media.
2. Chemical resistance: Secondly, consider the chemical resistance of the V-ring. Different V-ring materials have different tolerances to different chemical media. For example, polytetrafluoroethylene (PTFE) V-rings have excellent corrosion resistance and are resistant to almost all chemical media, while graphite V-rings are suitable for media such as hot water, high-temperature and high-pressure steam.
3. Cost-effectiveness: Finally, consider cost-effectiveness. Although high-performance V-ring materials may have better chemical resistance, they may also cost more. Therefore, when selecting chemical media, it is necessary to balance the relationship between performance and cost and select the most cost-effective material.
2. Common chemical media and their applicable V-ring materials
The following are several common chemical media and their applicable V-ring materials:

Please note that the above is only a general guide, and the specific selection needs to be made according to the actual situation and specific product specifications. When selecting V-ring materials, it is best to consult a professional seal manufacturer or supplier to obtain the most accurate advice.
