Ashcroft 95484XLL Pressure Gauge 0-30 Psi 2.5 in Lower Mount

Product Description

The ASHCROFT 95484XLL is an analog pressure gauge designed for accurate pressure monitoring in plumbing, HVAC, and industrial fluid systems. It features a 2.5-inch dial with a 0 to 30 psi range, making it well suited for low-pressure applications where precise readings matter. The gauge is dry-fill (no liquid filler) and uses a lower-mount, 1/4-inch threaded connection for direct inline installation. Both the case and wetted parts are constructed from 316 stainless steel, providing corrosion resistance in demanding service environments. Accuracy is rated at 3-2-3 percent of scale. Licensed plumbers, HVAC technicians, and mechanical contractors typically specify this gauge for system pressure verification and ongoing monitoring tasks.

This gauge is appropriate for residential and light commercial applications involving water, air, and compatible fluid systems. The 0 to 30 psi range covers common low-pressure service scenarios such as domestic water supply monitoring, compressed air circuits, and hydronic heating systems. The lower-mount configuration allows direct installation on threaded ports, manifolds, and tee fittings without additional adapters in most standard setups. The stainless steel construction makes it a practical choice in wet or corrosive environments where brass-body gauges may not be suitable.

Key Features

• 0 to 30 psi pressure range suited for low-pressure fluid and air service
• 2.5-inch analog dial for clear, readable display at typical working distances
• 316 stainless steel case and wetted parts for corrosion resistance
• Dry-fill (no-fill) design — no silicone or glycerin fill to manage or replace
• Lower-mount, 1/4-inch threaded connection for straightforward inline installation
• 3-2-3 percent of scale accuracy meets standard mechanical gauge requirements

Compatibility

Designed as an OEM-style replacement or new-installation analog pressure gauge for systems requiring a 1/4-inch lower-mount threaded connection and a 0 to 30 psi measurement range.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor. Isolate and depressurize the system completely before removing any existing gauge or installing this unit. Apply thread sealant tape or approved pipe dope to the male threads before seating the gauge — do not overtighten, as stainless steel fittings can gall. After installation, slowly repressurize the system and verify there are no leaks at the connection point before returning the system to service.
