Air Filled Pressure Gauge 1-100 PSI

Monitor Your RO System Like a Pro – With a Quick-Connect Pressure Gauge

Maintaining the right PSI is critical to keeping your reverse osmosis (RO) system running at peak performance. Low water pressure is one of the most common reasons for poor RO output, and this simple gauge helps eliminate the guesswork.

Easily installed in-line before your RO membrane, this air-filled pressure gauge comes pre-assembled with 1/4" quick-connect fittings—just plug and go. It not only confirms you're running at optimal pressure but also alerts you to pressure drops, a key sign that your sediment or carbon filters may need replacing.

Specifically designed for saltwater aquarium RO systems, this compact and reliable tool helps you stay ahead of maintenance and protect your water quality.
