Notes on coupling chemical resistance data

1. This chemical resistance information is created based on immersion tests of press sheets for the flow passages (inner surfaces) of couplings, and is not data for actual product use.
2. Because actual results may vary depending on usage conditions, including temperature, pressure, concentration, and time, the values shown in this table are only to be used for reference and do not guarantee the performance of our products.
3. When using chemicals, we ask that users check usability with the actual devices and usage conditions before use.
4. Tubes should not be used with gases that pose a risk of danger if permeation occurs (such as active gases). Always check the precautions for each product or contact us whenever necessary.
5. Unless otherwise specified, aqueous solutions are at a saturated concentration and room temperature.

Note: This data may change due to changes in product specifications or new information.
