Use these gauges with pumps, filters, regulators, and in process lines to monitor the pressure of compressed gas. Mount them with the dial face upright. Gauges for use with acetylene can also be used in welding applications.
Gauges with brass case are cleaned to meet ASME B40.1, Level IV for oxygen service.
Gauges with 304 stainless steel case are cleaned and bagged to meet ASME B40.1, Level IV for oxygen service.
