Ashcroft 95488XLL Pressure Gauge 0-200 Psi 2.5 in Lower Mount

Product Description

The ASHCROFT 95488XLL is an analog pressure gauge designed for accurate pressure monitoring in industrial, mechanical, and process piping applications. It features a 2.5-inch dial with a measurement range of 0 to 200 psi and a 3-2-3 percent of scale accuracy rating, meaning error stays within 3 percent at the lower and upper ends of the scale and within 2 percent through the mid-range. The case and all wetted parts are constructed from 316 stainless steel, making it suitable for corrosive media and harsh service environments. This gauge mounts from the lower port, which is the standard bottom-entry configuration found on most pipe and manifold installations. It is installed by plumbers, pipefitters, HVAC technicians, and industrial maintenance personnel.

This gauge is suited for residential and commercial plumbing systems, HVAC hydronic loops, compressed air lines, pump discharge and suction monitoring, and general process piping where a dry, non-liquid-filled gauge meets service requirements. The 1/4 inch lower-mount connection is a widely used thread size that fits directly onto standard gauge ports, valve manifolds, and tee fittings without adapters in most installations. The dry, no-fill design keeps maintenance simple and suits environments where temperature swings are not extreme enough to require glycerin or silicone fill dampening.

Key Features

• 0 to 200 psi measurement range suitable for a wide variety of plumbing and HVAC pressure monitoring tasks
• 3-2-3 percent of scale accuracy provides reliable mid-range and full-scale readings
• 316 stainless steel case and wetted parts resist corrosion in wet and mildly aggressive service environments
• 2.5-inch analog dial offers clear readability in tight mechanical rooms and equipment spaces
• Lower-mount 1/4 inch connection fits standard gauge ports without adapters in typical installations
• Dry no-fill design simplifies handling and suits moderate-vibration applications

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for systems with a standard 1/4 inch lower-mount gauge port rated within the 0 to 200 psi service range.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Isolate and depressurize the system completely before removing an existing gauge or installing this unit. Apply an appropriate thread sealant or PTFE tape to the male threads and tighten to the fitting using a wrench on the gauge hex, not the dial case. Follow applicable local plumbing codes and ASME B40.100 guidelines for pressure gauge installation and service.
