Ashcroft 94573XLL Pressure Gauge 0-30 Psi 2.5 in Dial

Product Description

The ASHCROFT 94573XLL is an industrial-grade analog pressure gauge built for demanding service environments. It features a 2.5-inch dial face with a 0 to 30 psi range and a lower-mount 1/4-inch MNPT connection, making it a straightforward drop-in for panel-mounted and pipe-mounted instrumentation installations. The case is 304/316 stainless steel and the wetted parts are bronze, providing corrosion resistance across a wide range of media. Accuracy is rated at 1 percent of scale, which meets requirements for most industrial monitoring applications. The lens is polycarbonate. No liquid fill is used in this configuration. Licensed tradespeople and instrumentation technicians working in HVAC, plumbing, and light industrial systems will find this gauge a direct fit for pressure monitoring points.

This gauge is suited for residential and commercial applications where a compact, durable pressure indicator is required. Common installation scenarios include boiler pressure monitoring, compressed air lines, water supply systems, and hydraulic circuits operating within the 0 to 30 psi range. The lower-mount MNPT fitting allows direct connection to threaded pipe or manifold ports. The analog dial provides at-a-glance readability without the need for a power source or signal wiring. The stainless steel case holds ratings of IP54 and IP65/NEMA 4, making it appropriate for wet or washdown-exposed locations.

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for industrial, commercial, and residential systems requiring a 1/4-inch MNPT lower-mount analog gauge rated to 30 psi.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or instrumentation technician. Depressurize and isolate the system completely before removing or installing any pressure gauge. Apply appropriate thread sealant to the MNPT fitting per the applicable plumbing or mechanical code. Do not over-tighten the fitting, as this can damage the gauge socket or distort the Bourdon tube.
