SUBMERSIBLE PRESSURE GAUGES ( SPG ) - OXYGEN CLEAN

While other manufacturers 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.

WARNING: All OMS^® Brass Glass SPG's while robust, are precision instruments and designed to be used with protective plastic boot (included). Failure to use this boot can result in catastrophic impact damage to the case causing Bourdon tube assembly and tempered glass lens failure. This damage is not covered under OMS^® warranty
