Ashcroft 95490XLL Pressure Gauge 0-400 Psi 2.5in Dial

Product Description

The ASHCROFT 95490XLL is an analog pressure gauge designed for industrial and mechanical system monitoring. It features a 2.5 inch dial with a 0 to 400 psi range and mounts via a 1/4 inch lower-mount connection. The stainless steel case and stainless steel wetted parts make it suitable for environments where corrosion resistance is required. Accuracy is rated at 3-2-3 percent of scale, meaning the gauge reads within 3 percent at the low and high ends of the scale and within 2 percent across the middle third. This is a dry-fill gauge with no liquid fill. It is commonly installed by HVAC technicians, plumbers, and industrial service professionals on pumps, compressors, pressure vessels, and piping systems.

The 95490XLL is suited for residential and light commercial mechanical systems as well as general industrial piping and pump applications. Its lower-mount configuration allows direct installation into process lines, manifolds, and equipment ports where a bottom-entry fitting is required. The 1/4 inch threaded connection is a standard size compatible with a wide range of threaded ports on pumps, compressors, and fluid-handling equipment. The dry case design keeps maintenance requirements low in clean, non-pulsating service conditions.

Key Features

• 0 to 400 psi pressure range suitable for a broad range of mechanical system applications
• 2.5 inch analog dial for clear on-site readings
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• 3-2-3 percent of scale accuracy across the full range
• Lower-mount, 1/4 inch threaded connection for direct in-line installation
• Dry fill (no liquid fill) construction for low-maintenance service

Compatibility

Designed as an OEM-style replacement or service gauge for mechanical systems requiring a 2.5 inch dial, lower-mount, 1/4 inch threaded pressure gauge rated to 400 psi.

Installation Notes

Installation should be performed by a qualified technician following applicable codes such as ASME B40.100 for pressure gauges. Depressurize and isolate the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on the 1/4 inch male threads and avoid over-tightening, which can damage the gauge socket. Do not install this dry-fill gauge in high-vibration or pulsating service without an external snubber or isolator.
