Ashcroft 82408XLL Pressure Gauge 2.5 in 0-600 Psi Lower Mount

Product Description

The ASHCROFT 82408XLL is an analog pressure gauge designed for industrial and mechanical system monitoring applications. It features a 2.5-inch dial diameter, a lower-mount 0.25-inch threaded connection, and a pressure range of 0 to 600 psi. The case and all wetted parts are constructed from stainless steel, making it suitable for use with mildly corrosive media and in environments where corrosion resistance is required. Accuracy is rated at 3-2-3 percent of scale across the dial range. This gauge ships without liquid fill, operating as a dry gauge. Licensed plumbers, HVAC technicians, and pipefitters are the primary installers for this type of instrument.

This gauge is well suited for residential and light commercial plumbing, HVAC, compressed air, and hydraulic system pressure monitoring. The lower-mount configuration positions the process connection at the bottom center of the gauge, making it appropriate for panel-mount or direct-pipe installations where a straight vertical or angled line connection is required. Its stainless steel wetted parts make it compatible with water, mild chemical, and compressed gas service lines, depending on system requirements and media compatibility verification.

Key Features

• 2.5-inch analog dial for clear, at-a-glance pressure readings
• Pressure range: 0 to 600 psi
• 3-2-3 percent of scale accuracy across the dial
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• Lower-mount, 0.25-inch threaded connection for direct pipe or panel installation
• Dry (no-fill) design — no liquid filler required

Compatibility

Designed as a general-purpose dry pressure gauge suitable for water, air, and compatible gas or fluid lines with working pressures within the 0 to 600 psi range and requiring a lower-mount 0.25-inch threaded connection.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and system requirements. Isolate and depressurize the system line before removing an existing gauge or installing this unit. Use appropriate thread sealant rated for the media type on the 0.25-inch male threads; do not overtighten, as this can damage the gauge socket. Verify that system pressure will not exceed the rated 600 psi range during normal or transient operating conditions.
