Ashcroft 96220 Pressure Gauge 4.5 in 0-300 Psi Rear Flange

Product Description

The ASHCROFT 96220 is a process industrial pressure gauge designed for demanding fluid and gas monitoring applications. It features a 4.5-inch analog dial with a measurement range of 0 to 300 psi and delivers 0.5% of scale accuracy. The gauge uses a 1/4-inch MNPT rear connection with a rear flange mount configuration, making it well suited for panel and bulkhead installations. The thermoplastic case paired with a glass lens and an IP66/NEMA 4X environmental rating gives this gauge solid resistance to dust, moisture, and washdown conditions. No liquid fill is used. Licensed trades and industrial maintenance personnel are the primary installers.

This gauge is intended for process and industrial environments where accurate, readable pressure indication is required at a fixed monitoring point. The 4.5-inch dial face provides clear visibility from a distance, and the rear flange mount allows secure attachment to instrument panels or enclosure walls. Typical applications include HVAC systems, compressed air lines, fluid process equipment, and general industrial piping where a permanent, panel-mounted gauge is needed. The CRN certification broadens its suitability for pressure vessel and piping installations in applicable jurisdictions.

Key Features

• 4.5-inch analog dial with 0 to 300 psi range for broad process monitoring coverage
• 0.5% of scale accuracy for reliable, repeatable pressure readings
• 1/4-inch MNPT rear connection with rear flange mount for panel installations
• Thermoplastic case with glass lens rated IP66/NEMA 4X for wet and dusty environments
• Non-liquid-filled design simplifies installation and eliminates fill-fluid compatibility concerns
• CRN certified and meets IP66/NEMA 4X standards for regulated and industrial use

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for process industrial piping and panel systems requiring a 1/4-inch MNPT rear-entry connection and rear flange mount.

Installation Notes

Installation should be performed by a qualified technician or licensed trades professional familiar with pressurized piping systems. Depressurize and isolate the system before removing or installing the gauge. Use appropriate thread sealant on the MNPT connection and tighten to the fitting manufacturer's specification without over-torquing the thermoplastic case. Verify that system pressure does not exceed the 300 psi maximum rating of the gauge.
