Series GG Gage Guard

Protective Instrument from Process Fluids

Protecting pressure or vacuum instruments from clogging, corrosion, or damage, the Series GG Gage Guard provides a protective barrier between the process fluid and the instrument. The hermetically-sealed uni-body protects from the possibility of leaking. Glass-filled Polypropylene housing is suitable for most inorganic chemicals and temperatures up to 185°F (85°C). A fluid fill station is recommended for proper installation.
