Ashcroft 95420XLL Pressure Gauge 0-1000 Psi 3.5 in Dial

Product Description

The ASHCROFT 95420XLL is a dry, analog pressure gauge designed for industrial and mechanical service applications requiring reliable pressure monitoring up to 1000 psi. It features a 3.5-inch dial for easy readability and a lower-mount 0.25-inch NPT connection for direct inline installation. The stainless steel case provides corrosion resistance in demanding environments, while bronze wetted parts suit a wide range of compatible media. Accuracy is rated at 1 percent of scale, meeting standard requirements for process monitoring, HVAC, plumbing, and fluid system diagnostics. This gauge is a non-liquid-filled, dry-type instrument suited for applications without high vibration or pulsation.

The 95420XLL is appropriate for residential and light commercial plumbing, HVAC refrigerant-side pressure testing, compressed air systems, and hydraulic monitoring where a permanent panel or inline gauge is needed. The lower-mount configuration allows direct vertical pipe connection, making it a common choice for manifold installations, pump discharge lines, and pressure test points. Licensed plumbers, HVAC technicians, and pipefitters typically specify this gauge for system commissioning and ongoing service diagnostics.

Key Features

• 3.5-inch analog dial for clear, at-a-glance pressure readings
• 0 to 1000 psi pressure range suits a broad range of system pressures
• 1 percent of scale accuracy meets standard process monitoring requirements
• Stainless steel case resists corrosion in wet or harsh environments
• Bronze wetted parts compatible with common system media
• Lower-mount 0.25-inch thread for direct inline or panel installation
• Dry-fill construction for low-vibration, stable-pressure applications

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for plumbing, HVAC, compressed air, and hydraulic systems using a lower-mount 0.25-inch threaded connection and requiring a 0 to 1000 psi range.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or pipefitter in accordance with applicable local codes and ASME B40.100 gauge standards. Shut off and depressurize the system completely before removing an existing gauge or threading in the new unit. Use appropriate thread sealant on the NPT connection and avoid over-tightening, which can crack the gauge socket. Do not install this dry-type gauge on systems with high vibration or severe pulsation without an appropriate snubber or isolator.
