While others use scratch prone plastic lenses and distortion prone plastic cases OMS® uses only scratch resistant tempered glass lenses (G-BU utilizes a plastic lens)and non distorting brass cases. All gauges use high precision Bourdon tube technology. The G-BU provides for a quick reading of your cylinder pressure and screws into the HP port of your regulator.

All SPGs include 32” HP hose, spool, and boot with the exception of the G-BU. Spg’s are oxygen cleaned prior to leaving the factory.
