Ashcroft 96227 Pressure Gauge 4.5 in 0-200 Psi Rear Flange

Product Description

The ASHCROFT 96227 is a process industrial pressure gauge designed for demanding fluid and gas pressure measurement applications. It features a 4.5-inch analog dial with a 0 to 200 psi range and delivers 0.5% of scale accuracy, making it suitable for systems where precise pressure readings are critical. The thermoplastic case resists corrosion and chemical exposure common in industrial environments. The glass lens provides clear dial visibility under normal service conditions. The 0.5-inch MNPT rear-mount connection and integral rear flange allow direct panel or pipe-wall installation. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers for this gauge type.

This gauge is well suited for process piping, HVAC systems, water treatment, compressed air lines, and general industrial fluid systems requiring a panel-mount or bulkhead-mount pressure indicator. The rear flange mount configuration positions the dial face flush against a panel surface, which is common in control room and skid-mounted system builds. The no-fill design simplifies installation where liquid-filled dampening is not required.

• 0 to 200 psi range with 0.5% of scale accuracy
• 0.5-inch MNPT rear connection suits standard pipe thread installations
• Rear flange mount enables clean panel or bulkhead mounting
• Thermoplastic case offers corrosion and chemical resistance
• Glass lens for clear, durable dial protection
• Rated to CRN and IP66/NEMA 4X standards for wet and washdown environments

Compatibility

Designed as an OEM-style process pressure gauge for industrial piping, HVAC, and fluid system applications requiring a 0.5-inch MNPT rear-entry, rear-flange-mount configuration with a 4.5-inch dial.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Isolate and depressurize the system fully before removing any existing gauge or fitting the new gauge. Apply thread sealant tape or paste appropriate to the process media on the MNPT threads. Do not over-torque the connection; hand-tighten and use a wrench only to achieve a leak-free seal per applicable piping codes such as ASME B31.1 or B31.3.
