Ashcroft 83206 Pressure Gauge 3.5 in Dial Npt Center Back

Product Description

The ASHCROFT 83206 is an analog pressure gauge designed for accurate pressure monitoring across a range of -30 to 60 in Hg. Built with a stainless steel case and a 3.5-inch dial, it provides clear, readable measurements in demanding service environments. The liquid-filled design dampens needle vibration for stable readings under pulsating or fluctuating pressure conditions. Accuracy is rated at 1 percent of scale. Connection is via 1/4-inch NPT center back mount, making it compatible with standard pipe fittings used in HVAC, plumbing, refrigeration, and industrial applications. This gauge is typically installed by licensed HVAC technicians, plumbers, and pipefitters.

The ASHCROFT 83206 suits residential and commercial applications where vacuum and low-pressure monitoring is required, including refrigeration system evacuation checks, HVAC line testing, and general utility piping. The center back mount configuration allows for flush or panel-style installation. Its -30 to 60 in Hg range covers both vacuum and positive pressure readings, making it useful for systems that operate across that span. The stainless steel case handles exposure to moisture and moderate corrosive environments better than standard painted-steel alternatives.

Key Features

• Liquid-filled dial for vibration and pulsation dampening in active systems
• 1 percent of scale accuracy for reliable readings across the full range
• 3.5-inch analog dial for high visibility in panel or field installations
• Stainless steel case resists corrosion and moisture in harsh service environments
• 1/4-inch NPT center back mount for straightforward in-line or panel installation
• Dual-range scale covering -30 to 0 to 60 in Hg for vacuum and positive pressure readings

Compatibility

Designed as an OEM-style or replacement pressure gauge for systems requiring a 1/4-inch NPT center back mount connection with a -30 to 60 in Hg measurement range.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Isolate and depressurize the system completely before removing an existing gauge or installing a new one. Use appropriate thread sealant on NPT fittings and avoid overtightening, which can damage the gauge body or distort readings. Verify that the system pressure range falls within the gauge rating before placing the system back in service.
