Ashcroft 94485 Pressure Gauge 0-60 Psi 3-1/2 in Lower Mount

Product Description

The ASHCROFT 94485 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in demanding service environments. It features a 3-1/2 inch analog dial with a 0 to 60 psi range and delivers 1% of scale accuracy. The stainless steel case and 316 stainless steel Bourdon tube provide corrosion resistance suitable for harsh or wet conditions. Liquid fill dampens needle vibration and reduces wear on internal components during pulsating or dynamic pressure applications. The 1/4 inch NPT lower mount connection allows direct inline installation on pipes, manifolds, and process equipment. Licensed plumbers, HVAC technicians, and industrial service professionals typically install this gauge.

This gauge is suited for residential and commercial plumbing systems, HVAC hydronic circuits, compressed air lines, and general industrial process piping where a reliable, vibration-resistant pressure readout is required. The lower mount configuration makes it appropriate for installations where the gauge sits upright above the process connection. The liquid-filled design is especially useful on equipment with compressors, pumps, or pressure-regulating valves that generate cyclic pressure fluctuations.

Key Features

• 0 to 60 psi range with 1% of scale accuracy for precise pressure readings
• Liquid-filled construction dampens vibration and protects the Bourdon tube
• 316 stainless steel Bourdon tube resists corrosion in wet and chemical-exposed environments
• 304/316 stainless steel case rated for IP54 and IP65/NEMA 4 ingress protection
• Polycarbonate lens provides impact resistance and clear dial visibility
• 1/4 inch NPT lower mount for standard inline pipe connection
• Meets CRN, PED, and RoHS standards

Compatibility

Designed as an OEM-style or replacement industrial pressure gauge for systems using a 1/4 inch NPT lower mount connection and requiring a 0 to 60 psi range on a 3-1/2 inch dial.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician following applicable IPC and local code requirements. Shut off and depressurize the system completely before removing an existing gauge or installing this unit. Use appropriate thread sealant compatible with the process fluid on the NPT threads — do not over-tighten, as stainless fittings can gall. Verify that the process pressure will not exceed the gauge maximum of 60 psi during operation or transient events.
