Ashcroft 92998 Pressure Gauge 0-600 Psi 6 in Dial Npt

Product Description

The ASHCROFT 92998 is an analog pressure gauge designed for accurate pressure measurement in industrial, HVAC, plumbing, and mechanical systems. It features a 6-inch aluminum-case dial with a 0 to 600 psi range and delivers 0.25 percent of scale accuracy, making it suitable for applications where precise readings are critical. The Bourdon tube is constructed from Monel, offering corrosion resistance in demanding service environments. Connection is via a 1/4-inch NPT lower-mount fitting. Licensed techs and journeymen plumbers install this gauge in line with pressure systems to monitor operating conditions and verify system integrity.

This gauge is used in residential and commercial applications where a large, easy-to-read 6-inch dial is needed for pressure monitoring. Lower-mount NPT connection makes it compatible with standard pipe tees, manifolds, and panel-mount setups. The glass lens and analog dial provide a clear, distortion-free view of the pointer. The CRN certification supports use in Canadian pressure vessel and piping installations, making it a practical choice for cross-border service contractors working to applicable pressure codes.

Key Features

• 0 to 600 psi pressure range suitable for a wide variety of system pressures
• 0.25 percent of scale accuracy for reliable, repeatable readings
• Monel Bourdon tube provides corrosion resistance in aggressive media
• 6-inch analog dial with glass lens for clear, unobstructed visibility
• 1/4-inch NPT lower-mount connection for standard pipe fittings
• Aluminum case construction keeps weight low for panel and inline installations
• CRN certified for use in Canadian pressure system applications

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for systems requiring a 1/4-inch NPT lower-mount connection and a 0 to 600 psi measurement range. CRN certification supports compliance with Canadian Registration Number requirements for pressure equipment.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local and national pressure piping codes. Isolate and depressurize the system completely before removing an existing gauge or installing this unit. Apply appropriate thread sealant to the NPT connection threads — do not overtighten, as this can damage the gauge socket. Verify the system operating pressure falls within the 0 to 600 psi range before returning the system to service.
