Ashcroft 94590XLL Dry Pressure Gauge 0-600 Psi 2.5in Lower Mount

Product Description

The ASHCROFT 94590XLL is a dry analog pressure gauge designed for accurate pressure measurement in plumbing, HVAC, and industrial piping applications. It features a 2.5-inch dial with a 0 to 600 psi range and delivers 1% of scale accuracy for reliable readings in demanding service environments. The stainless steel case provides corrosion resistance, while bronze wetted parts suit a broad range of compatible media. Mounting is via a lower 1/4-inch threaded connection, positioning the gauge inline or on a manifold fitting. Licensed plumbers, HVAC technicians, and pipefitters typically spec this gauge for system commissioning, leak testing, and ongoing pressure monitoring.

This gauge is suited for residential and light commercial systems where a compact, non-liquid-filled pressure gauge is required. The lower-mount configuration makes it well-matched for panel cutouts, manifold headers, and tee fittings where a straight stem connection is needed. The dry construction eliminates liquid fill concerns in freeze-prone or vibration-sensitive environments where a filled gauge would not be appropriate. The analog dial provides immediate visual indication without the need for external power or instrumentation.

Key Features

• 0 to 600 psi pressure range covers a wide range of commercial and residential service pressures
• 1% of scale accuracy provides reliable readings for system diagnostics and commissioning
• 2.5-inch analog dial offers clear, at-a-glance pressure readings
• Lower 1/4-inch threaded mount fits standard NPT fittings on manifolds and tee connections
• Stainless steel case resists corrosion in wet or outdoor service environments
• Bronze wetted parts compatible with a broad range of common system media
• Dry gauge construction requires no liquid fill maintenance or disposal considerations

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for systems requiring a 1/4-inch lower-mount dry gauge with a 0 to 600 psi range and a 2.5-inch dial.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes. Always depressurize and isolate the system before connecting or removing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per standard practice, being careful not to overtighten and crack the gauge socket. Do not exceed the rated maximum pressure of 600 psi during operation or testing.
