Ashcroft 94330 Pressure Gauge 0-200 Psi 2.5 in Dial Npt

Product Description

The ASHCROFT 94330 is an analog industrial pressure gauge designed for accurate pressure measurement in a wide range of mechanical and process applications. It features a 2.5-inch dial, a lower-mount 1/4-inch NPT connection, and a stainless steel case. The gauge reads 0 to 200 psi with 1% of scale accuracy. The Bourdon tube is constructed from 316 stainless steel for corrosion resistance, and the lens is polycarbonate. This is a dry (non-liquid-filled) gauge suited for installations where vibration damping is not required. HVAC technicians, plumbers, and industrial maintenance professionals are the typical installers.

The ASHCROFT 94330 is appropriate for residential and commercial mechanical systems where a reliable, lower-mount pressure gauge is needed on pipework, pressure vessels, compressors, or pump systems. The 1/4-inch NPT lower-mount configuration suits panel-mounted or inline pipe installations. Its stainless steel construction makes it a practical choice for environments with moisture, mild corrosives, or washdown exposure. Certifications include CRN, IP54, IP65/NEMA 4, PED, and RoHS, supporting use in both domestic and select international installations.

Key Features

• 2.5-inch analog dial with 0 to 200 psi measurement range
• 1% of scale accuracy for reliable pressure readings
• 316 stainless steel Bourdon tube for corrosion resistance
• 304/316 stainless steel case for durability in harsh environments
• Polycarbonate lens resists impact and moisture
• Certified to CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or direct-install industrial pressure gauge for systems using a lower-mount 1/4-inch NPT connection with a 0 to 200 psi operating range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician in accordance with applicable local codes and ASME B40.100 guidelines. Depressurize and isolate the system completely before removing an existing gauge or installing this unit. Apply thread sealant appropriate for the media and pressure rating to the NPT threads; do not overtighten, as this can damage the gauge socket. Verify the process pressure does not exceed the 200 psi maximum rating of this gauge.
