Dry & Liquid Process, Pressure, and Vacuum Gauges - 399


The below pressure gauges are used to measure air, water, and oil in general duty applications. They meet ANSI/ASME Grade 1A requirements. We stock a "dry" model or the "liquid filled" style. The liquid filled are waterproof and are typically used in applications subject to moisture, vibration, or pulsation. Our dry gauges have a black steel casing with brass internals and our liquid filled have a 304 stainless steel case, polycarbonate lens, brass internals, and glycerin liquid fill (silicone filled is recommended for applications where there's higher temperatures or prolonged exposure to UV). The glycerin liquid filled are rated for -10°C (14°F) to +65°C (149°F) and the dry gauges are rated for-40°C (-40°F) to +65°C (149°F). We recommend the use of our N602/603 Pressure Snubbers with all gauges to prevent 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 the pin hole at the gauge threads. How to select 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. Refer to HosePro "Did You Know" installation recommendation for liquid filled gauges listed in this section.
