Description
Duro-United Vacuum Gauge 30 In Hg 100 XkPa 1/4 NPT 2-1/2 Inch Face Dual Scale
This Duro-United analog vacuum gauge features a 2-1/2 inch dial face with a dual-scale readout displaying vacuum in both inches of mercury (in Hg) and XkPa (×100 kPa), covering a range of 0 to –30 in Hg and 0 to –100 XkPa. The gauge uses a bottom-mount 1/4 NPT brass fitting and houses the mechanism in a black case. The dial is clearly printed with Hg, XkPa, and bar reference markings, making it straightforward to read across unit systems.

Applications
Analog vacuum gauges like this Duro-United unit are standard instruments wherever vacuum levels need to be monitored and displayed locally. Common applications include vacuum pumps, industrial process lines, laboratory vacuum systems, HVAC refrigerant evacuation, vacuum ovens, filtration systems, and pneumatic controls. The dual Hg/kPa scale makes this gauge compatible with both U.S. customary and metric system setups, which is practical in mixed-standard industrial and lab environments. Bottom-mount 1/4 NPT connection is one of the most widely used thread standards in industrial instrumentation, making this gauge easy to fit into existing manifolds, tees, or vacuum lines without adapters in most cases.
This Duro-United 2-1/2" vacuum gauge (0–30 in Hg / 0–100 XkPa) is in good used condition. The dial face is clean and legible, with the dual Hg and XkPa scales clearly visible. The black case shows light surface wear consistent with prior use, and the brass 1/4 NPT bottom-mount fitting is intact with no visible damage. The needle appears to rest at zero. It was pulled from a working environment and has not been powered up or bench-tested at our facility. Please view our photo set and contact us if you have any questions.
