Iso-Ring Gauge Isolation Ring & Gauging Products

Out With the Old. In With the New.

OPW’s ISO-Ring® prevents solids within the process flow from plugging the pressure-sensing mechanism. And, unlike traditional diaphragm seals, it won’t clog.

With the patented isolation ring, process flow is uninterrupted and pressure readings are consistently reliable and accurate. On top of that, it’s easy to maintain and helps protect your instrumentation. There’s simply no better solution for viscous fluid applications.
