Industry Overview

GARHOPE special gas gauges are engineered for fire suppression, medical oxygen, LPG & gas filling and industrial gas service. Fire extinguisher gauges (25Z / 30Z) mount directly onto extinguisher valve heads with a coloured three-zone dial and extinguishing-agent type codes (F dry powder / S water-based / J clean gas). Oxygen regulator gauges (Y50 / Y60) use a fully oil- and grease-free copper internal construction, strictly degreased, with a red "USE NO OIL" mark on the dial. The LPG fill valve gauge assembly (Y50) combines the gauge with a filling valve for LPG cylinder filling stations.
