Ashcroft 92964XLL Pressure Gauge 4.5 in Rear Flange Mount

Product Description

The ASHCROFT 92964XLL is an analog pressure gauge built for accurate pressure monitoring in mechanical, HVAC, plumbing, and industrial service applications. It features a 4.5-inch dial for easy readout at a distance, a rear flange mount configuration, and a thermoplastic case suited for general-purpose environments. The gauge operates on a 0 to 15 psi range with an accuracy rating of 0.5 percent of scale, making it a reliable choice where precise low-range pressure readings matter. It is a dry, no-fill gauge with a 0.5-inch threaded connection. Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics in panel or wall-mount setups.

The 92964XLL is well-suited for low-pressure monitoring on water systems, air lines, gas distribution panels, and HVAC equipment. The rear flange mount design allows for direct panel or bulkhead installation, keeping the gauge face flush and readable. The 4.5-inch dial size is a common choice for control panels and equipment rooms where visibility across a workspace is needed. The dry thermoplastic case keeps the unit lightweight and resistant to common corrosive atmospheres encountered in mechanical rooms and utility spaces.

Key Features

• 4.5-inch analog dial for clear readability at a distance
• 0 to 15 psi pressure range suited for low-pressure service
• 0.5 percent of scale accuracy for reliable, precise readings
• Rear flange mount for direct panel or bulkhead installation
• Thermoplastic case — lightweight and corrosion-resistant
• Dry, no-fill design — no liquid filler required

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for low-pressure monitoring applications in HVAC, plumbing, water, and air systems requiring a rear flange mount configuration with a 0.5-inch threaded connection.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or pipefitter in accordance with applicable local codes and ASME B40.100 gauge installation standards. Shut off and depressurize the system fully before removing or installing any gauge. Use appropriate thread sealant on the 0.5-inch connection and avoid over-tightening, which can damage the thermoplastic case or the threaded port. Verify the system operating pressure falls within the 0 to 15 psi range before placing the gauge in service.
