Water Filtration Pressure Gauge – 0–300 PSI Side Mount

The Water Filtration Pressure Gauge with a 0–300 PSI range provides clear, dependable pressure monitoring for high-pressure reverse osmosis, commercial filtration, water treatment, and industrial process-water systems. Its side-mount configuration supports installation in compatible piping, equipment assemblies, and treatment systems where a front-facing dial is required for convenient viewing.

The easy-to-read dial helps operators monitor pressure levels and recognize changes that may indicate clogged filters, restricted flow, pump concerns, membrane conditions, or other system issues. Its corrosion-resistant stainless steel case provides durability in demanding commercial and industrial water-treatment environments.

With a measurement range of 0–300 PSI, this gauge is suitable for systems operating beyond the range of standard 100, 150, or 200 PSI pressure gauges. It is a practical monitoring component for equipment manufacturers, water-treatment dealers, system assemblers, service technicians, and facility-maintenance professionals.
