1/2" Compression Gauge Hydro Systems 50% Derived From:Glycerin Filled Gauge with 1 2" Compression Base This gauge attaches with a male compression fitting tube stub. The tube stub size will be the OD of the compression pipe fitting. The gauge is resistant to contamination using the included set screw within the valve stem. The set screw can be removed to give immediate feedback to rapidly changing pressures, it will open the gauge to contamination and possible damage if the pressure changes are too
