Ashcroft 251009A02BXLL1K Pressure Gauge 2.5 in Dial

Product Description

The ASHCROFT 251009A02BXLL1K is an analog pressure gauge built for accurate pressure measurement in mechanical, HVAC, plumbing, and industrial service applications. It features a 2.5-inch dial with a pressure range of 0 to 1000 psi and delivers 1% of full-scale accuracy. The stainless steel case provides corrosion resistance in demanding environments, while bronze wetted parts offer compatibility with a wide range of system media. This is a dry (no-fill) gauge, meaning it contains no liquid dampening fluid. Licensed tradespeople and service technicians use this gauge for system commissioning, diagnostics, and pressure verification tasks.

This gauge is suited for residential and commercial applications where a compact, back-mount analog gauge is required. The center back mount configuration allows direct panel or pipe installation where a rear-entry connection is preferred. With a 1/4-inch threaded connection and a 2.5-inch dial face, it fits standard gauge ports found in HVAC, plumbing, and fluid system installations. The dry construction makes it appropriate for environments where vibration and pulsation are not primary concerns.

Key Features

• 0 to 1000 psi pressure range for high-pressure system monitoring
• 1% of full-scale accuracy for reliable diagnostic and commissioning readings
• 2.5-inch analog dial for clear, direct visual readout
• Stainless steel case for corrosion resistance in harsh environments
• Bronze wetted parts compatible with common system media
• Dry (no-fill) construction — no liquid dampening fluid
• Center back mount with 1/4-inch thread for straightforward panel or pipe installation

Compatibility

Designed as an OEM-style replacement or direct-install analog pressure gauge for residential and commercial mechanical systems requiring a 1/4-inch center back mount configuration and a 0 to 1000 psi range.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor in accordance with applicable local codes. Depressurize and isolate the system completely before removing any existing gauge or installing this unit. Apply appropriate thread sealant to the 1/4-inch male threads — do not overtighten, as this can damage the gauge fitting or the port. After installation, pressurize the system slowly and verify the gauge reads within expected parameters before returning the system to service.
