Ashcroft 92900 Pressure Gauge 300 Psi 8.5 Inch Dial

Product Description

The ASHCROFT 92900 is an analog pressure gauge designed for accurate pressure monitoring in mechanical, HVAC, plumbing, and industrial service applications. The gauge features an 8.5-inch dial with a 0 to 300 psi range and delivers a measurement accuracy of 0.25 percent of scale, making it suitable for installations where precise readings are critical. The bourdon tube is constructed from bronze, and the case is aluminum. It uses a 1/4-inch lower mount connection, positioning the port at the six-o-clock position for direct panel or pipe mounting. Licensed tradespeople working in commercial and industrial environments rely on this gauge for process monitoring and system diagnostics.

The ASHCROFT 92900 is well suited for use in commercial HVAC systems, hydronic heating and cooling circuits, compressed air lines, and general plumbing pressure monitoring. The large 8.5-inch dial improves readability at a distance, which is particularly useful in mechanical rooms, boiler rooms, and equipment skids where instrumentation may be mounted away from eye level. The lower mount configuration is the standard choice for panel-mount and pipe-top installations where the supply line enters from below.

Key Features

• 8.5-inch analog dial for long-distance readability in mechanical room environments
• 0 to 300 psi pressure range covers a wide variety of HVAC and plumbing service conditions
• 0.25 percent of scale accuracy for precise pressure measurement
• Bronze bourdon tube provides reliable performance in typical water and air service media
• Aluminum case keeps overall weight manageable for panel and pipe mounting
• 1/4-inch lower mount connection suits standard pipe-top and panel installations

Compatibility

Designed as an OEM-style replacement or new-installation gauge for commercial HVAC, hydronic, plumbing, and compressed air systems requiring a lower-mount analog pressure gauge with a 1/4-inch connection and 8.5-inch dial.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or pipefitter in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Isolate and depressurize the system fully before removing any existing gauge or fitting the new one. Use appropriate thread sealant on the 1/4-inch NPT connection and avoid overtightening, which can crack the socket or case. Do not use this gauge in service with media that is incompatible with bronze or aluminum without consulting the manufacturer specifications.
