Ashcroft 94212 Pressure Gauge 0-1000 Psi 2.5in Dial Npt

Product Description

The ASHCROFT 94212 is a liquid-filled industrial pressure gauge designed for accurate, reliable pressure monitoring in demanding service environments. It features a 2.5-inch analog dial with a 0 to 1000 psi range and a 1/4-inch NPT lower-mount connection. The liquid fill dampens needle vibration and reduces internal condensation, making it well-suited for systems with pulsating pressure or mechanical shock. The stainless steel case and polycarbonate lens protect the movement in wet, corrosive, or washdown-rated locations. Accuracy is rated at 1 percent of scale across the full range.

This gauge is appropriate for use in commercial and industrial plumbing, hydraulic systems, compressed air lines, chemical processing, and HVAC chilled or hot water circuits. The lower-mount NPT connection allows direct installation into a threaded port on a pipe, manifold, or pressure tap without an additional adapter in most standard configurations. It is installed by licensed plumbers, pipefitters, HVAC mechanics, and industrial maintenance technicians.

Key Features

• Liquid-filled design suppresses needle flutter caused by pressure pulsation or vibration
• 0 to 1000 psi range on a 2.5-inch analog dial for clear readability at a distance
• 316 stainless steel Bourdon tube resists corrosion in aggressive media
• 304 and 316 stainless steel case construction for durable, long-service performance
• Polycarbonate lens provides impact and chemical resistance
• Meets CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed for use in industrial and commercial pressure measurement applications requiring a 1/4-inch NPT lower-mount connection and a 0 to 1000 psi operating range. Consult system documentation to confirm port size, pressure rating, and media compatibility before installation.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified industrial technician. Isolate and depressurize the system completely before removing or installing any pressure gauge. Apply appropriate thread sealant to the NPT threads in accordance with the applicable plumbing or piping code. Do not use the dial or case as leverage when threading the gauge into the port; use a wrench on the hex fitting only to avoid damaging the internal movement.
