Ashcroft 94488 Pressure Gauge 0-200 Psi 3.5 in Dial Npt

Product Description

The ASHCROFT 94488 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in demanding service environments. It features a 3.5-inch analog dial with a 0 to 200 psi range and delivers 1% of scale accuracy. The case is constructed from 304/316 stainless steel, and the Bourdon tube is 316 stainless steel, making it well suited for corrosive or wet service conditions. A polycarbonate lens protects the dial face. The lower-mount, 1/4-inch NPT connection allows direct installation into pipe taps and manifolds. Licensed HVAC technicians, plumbers, and industrial maintenance professionals install this gauge in both new construction and service applications.

The 94488 is appropriate for residential and commercial systems where reliable pressure indication is required. Liquid-filled construction dampens needle vibration caused by pulsating flow or mechanical vibration, extending gauge service life and improving readability. The lower-mount NPT configuration suits panel-mount, pipe-tap, and equipment-port installations. This gauge is compliant with CRN, IP54, IP65/NEMA 4, PED, and RoHS standards, making it a practical choice for installations that require documented certifications.

Key Features

• Liquid-filled case dampens vibration and pulsation for stable readings
• 304/316 stainless steel case and 316 stainless steel Bourdon tube resist corrosion
• Polycarbonate lens provides impact and moisture resistance
• Lower-mount 1/4-inch NPT connection for direct pipe or equipment-port installation
• Certified to CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style and replacement industrial pressure gauge for systems with 1/4-inch NPT lower-mount pressure ports requiring a 0 to 200 psi range.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial maintenance professional. Depressurize and isolate the system before removing an existing gauge or installing this unit. Apply thread sealant or PTFE tape appropriate for the service medium to the NPT threads before installation. Do not over-tighten the threaded connection; use a wrench on the hex fitting body, not on the gauge case.
