Plast-O-Matic GGS Diaphragm Seal
Plast-O-Matic® series GGS gauge guards should be used to isolate and protect pressure or vacuum instruments used on ultra-pure or highly corrosive fluid lines. They can be confidently used with liquids such as de-mineralized water, sulphuric acid, hydrochloric acid, and caustics. Utilization of Plast-O-Matic gauge guards offers the added advantage of protection against clogging of instruments caused by suspended solids or highly viscous fluids. Plast-O-Matic gauge guards are available with or without gauges.
