Ashcroft 92963XLL Pressure Gauge 4.5 in 0-300 Psi Rear Flange

Product Description

The ASHCROFT 92963XLL is an analog pressure gauge designed for accurate pressure monitoring across a wide range of industrial and mechanical applications. It features a 4.5-inch dial for easy readability and a thermoplastic case for durability in demanding environments. The gauge measures pressure from 30 inches of vacuum to 300 PSI, with an accuracy rating of 0.5 percent of scale. Mounted via a rear flange configuration with a 0.25-inch threaded connection, this gauge is suited for permanent panel or wall installations where front-face access is limited. It ships without liquid fill, making it appropriate for dry-service environments.

This pressure gauge is commonly used in HVAC systems, plumbing installations, compressor monitoring, and general industrial process applications. The rear flange mount allows flush or panel-mount installations where the gauge face needs to sit flat against a surface. Licensed mechanical contractors, pipefitters, and HVAC technicians typically install this type of gauge during new system commissioning or as a direct replacement on existing pressure monitoring points.

Key Features

• 4.5-inch analog dial for clear readability at a distance
• Pressure range: 30 inches vacuum to 300 PSI
• 0.5 percent of scale accuracy for reliable readings
• Rear flange mount with 0.25-inch threaded connection for panel installations
• Thermoplastic case construction for lightweight durability
• Dry service, non-liquid-filled design

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for dry-service mechanical, HVAC, and plumbing systems requiring a rear flange mounted analog gauge with a 4.5-inch dial and 0.25-inch threaded port.

Installation Notes

Installation should be performed by a licensed mechanical contractor, plumber, or qualified HVAC technician. Shut off and depressurize the system completely before removing any existing gauge or making threaded connections. Apply appropriate thread sealant to the 0.25-inch connection per local code requirements. Ensure the rear flange is secured firmly to the panel surface before returning the system to operating pressure.
