Reliable operation up to 6 MPa

The GA-YQ1 Liquid Isolator is designed for reliable isolation of liquid media during pressure instrument calibration and maintenance. It is widely used for oxygen gauges, acetylene gauges, and other sensitive pressure devices.

By using a high-strength diaphragm, the isolator completely separates the upper and lower media chambers, preventing oil, water, and contaminants from mixing. This effectively protects calibration equipment and test instruments from external contamination.

With a pressure rating of up to 60 MPa, quick-connect M20×1.5 interfaces, and a large 120 mL upper chamber, the GA-YQ1 ensures stable pressure transmission and long-term operational reliability. Its simple filling and maintenance procedure makes it suitable for laboratories, calibration centers, and industrial service environments.
