Ashcroft 96230 Pressure Gauge 4.5 in Dial 0-600 Psi Rear Flange

Product Description

The ASHCROFT 96230 is an analog pressure gauge built for trade professionals who need reliable, accurate pressure readings in demanding service environments. With a 4.5-inch dial and a measurement range of 0 to 600 psi, this gauge delivers clear readability and a rated accuracy of 0.5 percent of scale. The thermoplastic case offers resistance to corrosion and impact in typical field conditions. The rear flange mount configuration allows the gauge to be surface-mounted directly to panels, walls, or equipment frames while keeping the process connection at the back. No liquid fill is used, making it straightforward to handle and install without the mess associated with glycerin or silicone-filled units.

This gauge is suited for HVAC, plumbing, and industrial process applications where a mid-range pressure gauge is required for monitoring system pressure at a fixed location. The 4.5-inch dial size is a common choice for control panels, mechanical rooms, and equipment skids where technicians need to read the gauge from a moderate distance. The rear flange mount style is a standard configuration in panel-mounted instrumentation setups found in commercial and light industrial facilities. Licensed HVAC technicians, pipefitters, and plumbers regularly specify this type of gauge for air, water, steam, and compatible gas service applications.

Key Features

• 0 to 600 psi pressure range covers a broad range of common system pressures
• 0.5 percent of scale accuracy provides reliable readings for service and monitoring tasks
• 4.5-inch analog dial offers clear visibility at a distance
• Rear flange mount allows panel or surface mounting with rear process connection
• Thermoplastic case resists corrosion without adding significant weight
• No liquid fill design simplifies handling and reduces contamination risk

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for panel-mounted and rear-flange applications in HVAC, plumbing, and light industrial systems requiring a 4.5-inch dial gauge with a 0 to 600 psi range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Always depressurize and isolate the system before removing an existing gauge or making new connections. Use appropriate thread sealant compatible with the system media on the 0.5-inch threaded process connection. Verify that the gauge range and media compatibility are appropriate for the system before placing into service.
