Ashcroft 92647 Pressure Gauge 0-300 Psi 6 in Dial Npt

Product Description

The ASHCROFT 92647 is an analog pressure gauge designed for accurate pressure monitoring across industrial, HVAC, plumbing, and mechanical system applications. It features a 6-inch aluminum case dial with a glass lens, a bronze Bourdon tube sensing element, and a 1/4-inch NPT lower-mount connection. The gauge reads 0 to 300 psi with an accuracy of 0.25 percent of scale, making it suitable for installations where reliable, easy-to-read pressure indication is required. Licensed trades including HVAC technicians, pipefitters, and plumbers install this type of gauge on pressure vessels, piping systems, compressors, and pumps where continuous pressure visibility is needed.

This gauge is a fit for residential and commercial mechanical systems that require a field-mounted analog pressure readout. The 6-inch dial provides clear visibility at a distance, and the lower-mount NPT configuration suits standard panel-mount or pipe-mount installations. The CRN certification indicates it meets Canadian Registration Number requirements for pressure-containing equipment, broadening its usability across jurisdictions that require that standard. It is commonly installed on hydronic heating systems, compressed air lines, water supply systems, and refrigerant or fluid distribution manifolds.

Key Features

• 0 to 300 psi pressure range with 0.25 percent of scale accuracy
• 6-inch analog dial for clear, at-a-distance readability
• Aluminum case with glass lens for durability and visibility
• Bronze Bourdon tube sensing element for broad fluid compatibility
• 1/4-inch NPT lower-mount connection for standard pipe installations
• CRN certified for use in jurisdictions requiring Canadian pressure equipment registration

Compatibility

Designed as an OEM-style or replacement analog pressure gauge for residential and commercial piping, HVAC, and mechanical systems requiring a 1/4-inch NPT lower-mount gauge with a 6-inch dial reading up to 300 psi.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Depressurize and isolate the system before removing an existing gauge or installing a new one. Apply appropriate thread sealant to the NPT threads in accordance with local plumbing or mechanical codes. Do not over-torque the brass or bronze fitting connections, as this can damage the tube or case.
