This collection covers Pasco pressure gauges for water, air and system testing. It includes 2 inch dial gauges in 30, 100, 160, 200 and 300 psi ranges, and 2-1/2 inch glycerine liquid-filled gauges in 30, 200 and 300 psi ranges.
Choose a range where the normal operating pressure reads in the middle third of the dial, and check the connection thread and bottom or back mount. Liquid-filled gauges dampen needle vibration from pumps and pulsation. Install a shut-off or snubber where the gauge may need replacement or sees pressure spikes.
