Ashcroft 92912 Pressure Gauge 3 in 0-100 Psi Npt Lower Mount

Product Description

The ASHCROFT 92912 is an analog pressure gauge designed for accurate pressure monitoring in industrial, mechanical, and HVAC applications. It features a 3-inch dial face with a 0 to 100 psi range, a lower-mount 1/4-inch NPT connection, and a 316 stainless steel Bourdon tube and case for corrosion resistance. Accuracy is rated at 0.5% of scale, which meets the demands of professional service work where precise readings are required. The polycarbonate lens resists impact and provides a clear view of the dial under field conditions. Weighing 2 pounds, this gauge is built for durable, long-service installation in demanding environments.

This gauge is well suited for use in plumbing systems, hydronic heating, compressed air lines, refrigeration equipment, and general fluid service applications. The lower-mount NPT configuration makes it a standard fit for pipe-thread installations in commercial and light industrial settings. Licensed plumbers, HVAC technicians, and pipefitters commonly install this style of gauge on pressure vessels, pump outlets, manifolds, and test ports where a permanent, readable pressure indication is required. The stainless steel construction makes it appropriate for mildly corrosive fluid service.

Key Features

• 3-inch analog dial for easy field readability
• 0 to 100 psi pressure range suitable for most low-to-medium pressure systems
• 316 stainless steel Bourdon tube and case for corrosion resistance
• 1/4-inch lower-mount NPT connection for standard pipe-thread installation
• 0.5% of scale accuracy for precise pressure readings
• Polycarbonate lens provides impact resistance and clear dial visibility
• CRN certified for use in Canadian pressure vessel applications

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for systems with a 1/4-inch NPT lower-mount port requiring a 3-inch dial, 0 to 100 psi analog gauge.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before removing any existing gauge or fitting. Apply an appropriate thread sealant to the NPT threads per the system fluid compatibility requirements. Do not overtighten the gauge connection, as this can damage the Bourdon tube or crack the case.
