  • Gaseous Service: Not designed for lightweight gases
  • Corrosion: Before ordering, verify all materials of our sight flow indicators are compatible with the service media(s), intermittently used cleaners, the environment, and cleaning processes in conjunction with the temperatures and pressures of the application(s) and future applications. John C. Ernst LLC. does not make chemical compatibility recommendations. Compatibility is the responsibility of the user.
