Ashcroft 91552XLL Pressure Gauge 4.5 in Dial 0-2000 Psi

Product Description

The ASHCROFT 91552XLL is an analog pressure gauge designed for industrial and commercial applications requiring reliable, accurate pressure monitoring. Featuring a 4.5-inch dial, this gauge delivers 0.5% of scale accuracy across a range of 0 to 2000 psi. The aluminum case keeps weight low while stainless steel wetted parts resist corrosion from process media. The rear flange mount configuration allows for direct panel or bulkhead installation in tight instrumentation setups. This gauge is installed by instrumentation technicians, HVAC engineers, plumbers, and industrial service professionals working on pressurized systems.

The 91552XLL is suited for residential and commercial pressurized piping systems, hydraulic circuits, air compressor panels, and process control installations where a sturdy, non-liquid-filled panel gauge is needed. The 0.5-inch threaded connection and rear flange mount make it a direct fit for panel cutout installations where front-accessible connections are not practical. Its dry, no-fill configuration makes it appropriate for clean gas and liquid service where liquid-filled dampening is not required.

Key Features

• 4.5-inch analog dial for easy reading at distance
• 0 to 2000 psi pressure range suitable for high-pressure process and hydraulic service
• 0.5% of scale accuracy for precise pressure indication
• Stainless steel wetted parts for corrosion resistance against aggressive media
• Aluminum case reduces overall weight without sacrificing structural integrity
• Rear flange mount design allows secure panel or bulkhead installation
• Dry, no-fill construction eliminates liquid fill leakage concerns

Compatibility

Designed as an OEM-style or direct-replacement analog pressure gauge for panel-mount instrumentation applications using a 0.5-inch threaded rear-entry connection with flange mounting.

Installation Notes

Installation should be performed by a qualified instrumentation technician, plumber, or mechanical contractor. Always depressurize and isolate the system before removing or installing any pressure gauge. Apply appropriate thread sealant to the male threads per the system fluid compatibility requirements, and do not overtighten the connection. Follow applicable codes including ASME B40.100 and local mechanical codes for gauge installation and pressure system service.
