Selection Guide
Choosing the Right Pressure Gauge
Determine Pressure Range
Identify the maximum operating pressure of your water filtration system. Select a gauge with a maximum scale reading that is 1.5 to 2 times your normal operating pressure to ensure accuracy and extend gauge life.
Select Connection Type
Choose between bottom stem mounting for direct pipe connection or center stem mounting for panel installation. All gauges feature standard 1/4" NPT threads compatible with most filtration system connections.
Consider Environment
Opt for stainless steel construction in corrosive environments or high-vibration applications. ABS gauges provide excellent value for standard indoor installations where chemical resistance is not a primary concern.
Professional Tip: Install pressure gauges on both the inlet and outlet sides of your filters to monitor differential pressure. A pressure drop of 15-20 PSI typically indicates it's time for filter replacement, preventing system strain and maintaining optimal water quality.
