Premium Dry & Liquid Process, Pressure & Vacuum Gauges - 400
How to select and install a pressure gauge? When selecting a pressure gauge, the ideal working pressure should be at the 12:00 position (pointing up) as the middle third is the most accurate. Note: Liquid gauges should be "burped" when installed, to allow for atmospheric or elevation pressure adjustment. We recommend the use of our N602/603 Pressure Snubbers with all gauges to prevent sediment clogging and reduce the damage caused by surges. Care must be used when applying pipe dope so it does not come into contact with the fluid or it can plug fine internals of the gauges - resulting in pinning.
