In-Line Pressure Regulators and Gauges

Most GC systems require that the pressure is regulated between the source (gas cylinder or gas generator) and the instrument. Select a pressure regulator based on the application:

  • In-Line Regulators: Reduce pressure in a single step. Choose an in-line regulator if a 1-stage gas cylinder regulator is used. Install the in-line regulator within 10 feet of the instrument. 400 psig maximum inlet pressure.

We offer several versions of in-line pressure regulators to serve a wide variety of needs.
