Precautions

  • *Using a positive-pressure gas with our plastic piping may pose a dangerous condition due to the repellent force peculiar to compressed fluids, even when the gas is under the same pressure as water. Therefore, be sure to take the necessary safety precautions such as covering the piping with protective material. For inquiries, please contact us.
    For conducting a leak test on newly installed piping, be sure to check for leaks under water pressure.
    If absolutely necessary to use gas in testing, please consult your nearest service station beforehand.
  • *Wrap the threaded joints on our plastic piping with sealing tape.
    Using a liquid sealing agent or liquid gasket may cause stress cracks (environmental stress cracking). Our product warranty shall not apply in case of said use, even when said use is unavoidable.
