Ashcroft 83217 Pressure Gauge 150 Psi 2.5 in Dial Npt

Product Description

The ASHCROFT 83217 is an analog pressure gauge designed for accurate pressure measurement in plumbing, HVAC, and industrial service applications. It features a 2.5-inch dial with a range of 30 inches of vacuum to 150 psi and delivers 1 percent of scale accuracy. The stainless steel case provides corrosion resistance in wet or chemically active environments. The gauge is liquid filled, which dampens needle vibration and extends service life in high-pulsation systems. It mounts via a lower 1/4-inch NPT connection and weighs 1.5 pounds. Licensed plumbers, HVAC technicians, and pipefitters install this gauge as part of pressure monitoring assemblies on pumps, boilers, chillers, and compressed air systems.

The ASHCROFT 83217 suits residential and light commercial installations where a compact, durable pressure gauge is required. Its lower-mount NPT configuration makes it compatible with standard pipe tees, manifolds, and pressure ports. The liquid-filled construction makes it a preferred choice in pump skids and equipment subject to vibration or pressure spikes. The stainless steel case holds up in damp mechanical rooms and outdoor-rated enclosures where painted or chrome-plated cases may corrode.

Key Features

• 150 psi maximum pressure rating with a full vacuum-to-pressure range of 30 inches vacuum to 150 psi
• 1 percent of scale accuracy for reliable field readings
• Liquid-filled dial dampens needle vibration in pulsating systems
• Stainless steel case resists corrosion in wet and chemical-exposure environments
• 2.5-inch analog dial for easy readability in tight equipment spaces
• Lower 1/4-inch NPT mount fits standard pipe fittings and manifolds

Compatibility

Designed as a direct-fit lower-mount pressure gauge for systems using 1/4-inch NPT pressure ports, including pumps, boilers, compressed air lines, and water supply assemblies.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Shut off and depressurize the system fully before removing or installing the gauge. Use thread sealant or PTFE tape on the NPT threads and tighten to fitting-manufacturer specifications using a wrench on the gauge hex only — do not apply torque through the dial housing. Verify the system pressure range does not exceed the gauge maximum rating before returning the system to service.
