The OBS-V Series Vacuum Plastic Pressure Gauge is the most accurate pressure gauge available, specifically designed for corrosive environments. With a thermoplastic polypropylene enclosure, the OBS-V Series gauges are engineered for durability in harsh, corrosive conditions.

Each OBS-V Plastic Pressure Gauge is equipped with a ¼” NPT 316SS connection, making it an ideal match for our GI Series Pressure Gauge Guards when dealing with highly corrosive chemicals. The gauge guards protect the pressure gauge from corrosive media in the system through an isolator.

Factory pre-filled, OBS-V gauges achieve exceptional accuracy (0.75%). Additionally, each gauge features movable color range tabs—red, yellow, and green—that serve as visual alerts for bag or filter change-outs.
