Application Notes:
- Saturated Steam Service: Upgraded gaskets and mica shields are recommended for saturated steam service. All ratings stated on our website and in our literature are non-steam ratings unless specified otherwise. Always contact our sales office for saturated steam ratings when needed.
- Vacuum Service: Acceptable when using with elastomer seals
- 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 Co. does not make chemical compatibility recommendations. Compatibility is the responsibility of the user.
