Ashcroft 82111XLL Pressure Gauge 2.5in Center Back Mount

Product Description

The ASHCROFT 82111XLL is an analog pressure gauge designed for accurate pressure measurement in industrial, commercial, and mechanical system applications. It features a 2.5-inch dial with a 0 to 1000 psi pressure range and delivers 1 percent of scale accuracy. The stainless steel case and stainless steel wetted parts make it well suited for environments where corrosion resistance is a priority. This is a dry-type gauge with no liquid fill. It mounts via a center back connection using a 1/4-inch thread. HVAC technicians, plumbers, and mechanical contractors install this type of gauge for system monitoring and diagnostic work.

This gauge fits typical applications where a compact, corrosion-resistant pressure instrument is needed on pipelines, pressure vessels, pumps, compressors, or HVAC refrigerant circuits. The center back mount configuration positions the dial face outward for easy reading when the gauge is installed directly into a panel or manifold. The 2.5-inch dial size is a standard trade size used across residential and light commercial mechanical systems.

Key Features

• Stainless steel case provides corrosion resistance in wet or chemically active environments
• Stainless steel wetted parts for compatibility with aggressive media
• 1 percent of scale accuracy for reliable pressure readings
• Dry gauge construction with no liquid fill, reducing leak risk
• Center back mount with 1/4-inch thread fits standard instrument connections
• 2.5-inch analog dial for clear, at-a-glance pressure monitoring

Compatibility

Designed as a direct-fit analog pressure gauge for systems requiring a 1/4-inch center back mount connection with a 2.5-inch dial and a 0 to 1000 psi range. Suitable for use on pipelines, pumps, compressors, and mechanical systems where a dry stainless steel gauge is specified.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or mechanical contractor. Depressurize and isolate the system completely before removing any existing gauge or fitting. Use appropriate thread sealant compatible with the system media on the 1/4-inch NPT connection. Verify the pressure range of the gauge does not exceed the operating pressure of the system being monitored.
