Ashcroft 92643 Pressure Gauge 0-30 Psi 6 Inch Dial

Product Description

The ASHCROFT 92643 is an analog pressure gauge designed for accurate pressure measurement in plumbing, HVAC, and industrial service applications. It features a 6-inch aluminum case dial with a 0 to 30 psi range and delivers 0.25 percent of scale accuracy, making it suitable for systems where reliable readings are critical. The lower-mount configuration accepts a 1/4-inch NPT connection, and the glass lens protects the analog face from moisture and debris. A bronze Bourdon tube provides the internal sensing element. Licensed plumbers, HVAC technicians, and pipefitters commonly install this gauge on low-pressure systems, test manifolds, and distribution panels.

The 92643 is well suited for residential and light commercial applications where low-pressure monitoring is required. Typical installations include domestic water supply lines, boiler feed systems, compressed air service, and hydronic heating circuits operating within the 0 to 30 psi range. The 6-inch dial size improves readability at distance, which is useful on mechanical room equipment and panel-mounted assemblies. The lower-mount NPT fitting simplifies installation on vertical risers and tee fittings. This gauge carries CRN certification, making it appropriate for use in Canadian-registered pressure vessel applications as well.

Compatibility

Designed as an OEM-style or replacement pressure gauge for low-pressure plumbing, HVAC hydronic, compressed air, and boiler feed systems using standard 1/4-inch NPT lower-mount connections with a 0 to 30 psi operating range.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Shut off and depressurize the system fully before removing an existing gauge or installing this unit. Apply thread sealant or PTFE tape to the NPT threads, but do not overtighten, as aluminum cases can be damaged by excess torque. Verify the system operating pressure falls within the 0 to 30 psi range before placing the gauge into service.
